there z always a chance of being correct so o% is out of the way remaining 3 options, two of which are the same, you either pick 25% or 50% i.e one of the two [1/2] giving us 50% as d correct option

Op you that knows it now are you richer than dangote is this helping you in anyway of your life. You see this is the reason why so many people are poor, instead of you to go and learn a high income skill that will help you in your life you are here calling people olodo because you can solve stupid math that they cannot solve. Please tell me where that math has taken you in life but I'm not surprised because it's not your fault, I blame school for all the useless youth we have in this country, so op instead of you to come here and tell us to solve stupid math please use your time to go and Learn a high income skill like copywriting, email marketing, SEO, Internet marketing etc and come and thank me later grin because this math you know will not take you anywhere.

IQ tests need to be mandatory to post here. So I am kicking it off with this very rudimentary test.

Provide reasons for your answer.

See pic below for test.
Firstly, since the first ball you selected is gold, then you are likely to have selected from either of 2 boxes.
Secondly, since you are thinking of selecting another gold ball, then your concern is on 1 box i.e. box with GG
Hence, the Pr(selecting another gold ball) = number of box with GG/total number of boxes = 1/3

Here is my explanation for test 1 assuming randomized boxes after 1st gold pick. Answer = 1/3 :

1. You start with one state. Lets call this state the GG/GS/SS state.

2. After picking a gold ball (P = 2/3), you now have two possible states: (1) GG/S/SS state OR (2) G/GS/SS state. The (1) is the state if the gold ball was picked from the GS box. And the (2) state is if the gold ball was picked from the GG box.

3. Assuming we are only interested in what happens after the 1st gold ball was picked. Then the probability of picking a second gold ball from the same box = (a) the prob. of picking from the same box in the GG/S/SS state + (a) the prob. of picking from the same box in the G/GS/SS state.

(a) = 0 since the same box only have a silver ball in it. (b) = 1/3 since the same box has one gold ball left in it and the prob. of picking that box is still 1/3.

Therefore the answer is: 0 + 1/3 = 1/3

Here is my explanation for test 2 answer 3/4 :


this is simply the probability of 25% been the answer (2/4) plus the probability of the correct answer if 25% is not the answer (1/4). Put in another way, basically, if 25% is NOT the answer then 3 of the options are wrong so that means the probability of getting right is 1/4. But if 25% is the answer then only 2 of the options are wrong, that means the probability of getting right is 2/4. The sum gives you 3/4.

Waiting for Test 3.

Well another way to it is that since it can either be the box with GG or GS, that means at the initial stage there are 3 G balls and 1 S ball that could be selected. Since selection is without replacement and a G ball had been selected, then there are 2 possible G balls left to be selected after initial selection i.e. 2 G balls and 1 S ball are left after initial selection. As such,
Pr(selecting G ball again) = number of G balls left ÷ number of total balls left
= 2/3

APCLyingBastard:



Let me put you out of your pathetic ignorance and misery.

let me provide the LOGIC behind the answer which is 1/2 or 50%.

You have 6 balls , 3 gold and 3 silver arranged in 3 boxes with 2 gold, 2 silver and one of either in separate boxes.

You draw a gold ball.

The question that was asked is what is the probability of you drawing a second ball from the same box?

That means you drew from either the box with 2 gold balls or the one with a single gold and silver ball.
Now you have only 3 balls left in two boxes where you had gold balls
The chances of you having drawn a gold ball from the box with either 2 gold balls or a single gold ball is inconsequential as the main question is the follow-up event of drawing a second ball.
Hence, you are left with deciding if your first draw was from either the box with 2 gold balls or the one with a single gold and a single silver ball.
The probability that you will pick a gold ball is 50% because if you drew from the first box with 2 gold balls , it would have been 100% but then again you might have drawn from the second box with a single gold ball and a silver ball.
So you are either going to pick a Gold ball (if you selected from the first box) or a silver ball (if your first draw was from the second).


The answer is 1/2 ONLY if the boxes are not randomized after the 1st gold pick. If the are randomized the answer is 1/3.

Solution for non-randomized boxes after 1st gold pick: There are 2 possibilities - (1) GG/S/SS state or G/GS/SS state. In (1) I end up with a G. And in (2) I end up with a silver. It heads or tails hence 1/2.

Solution for randomized boxes after 1st gold pick: If you draw the first gold ball from the GG box then your probability of drawing the 2nd gold ball from the same box is 1/3 (i.e the probability of randomly picking this box from the 3 available boxes). Now if the 1st gold ball was drawn from the GS box then the probability of picking the second gold ball from the same box is 0. (because even though the probability of picking that box is also 1/3, the prob. of finding a gold ball in it is zero since that box has just the silver ball in it). Therefore the probability is: 1/3 + 0 = 1/3..
Re: If You Fail This Test, Then Stop Posting Here by calgenius: 3:57am On May 24
@OP d ansa is 1/2(i.e 50%)..
explanation

first we have 3 boxes each having 2balls.

no of of gold b in box1=2
no of gld bal in box2=1
no of gld bal in box3=0

since d first bal picked is a gold ball, then it must be picked frm either box1 or box2 (since box 3 doesnt have a gold bal)..

if its box1 then,

the prob.of picking second gold bal=1

if its box2 then,

the prob. of picking second bal as gold bal =1/2

NOW, probability of picking second bal as gold=(pr of picking in box1 *pr of picking it in box2)=(1*1/2)=1/2 ANS

I would say 1/9.
I'm looking beyond the balls to focus on the box instead.
Choose same box twice.
The reason for me doing this is that the question is really centered on the box. By eliminating two boxes from the question, it's quite obvious their balls don't count.
