In a very dark cupboard there is a heap of twenty socks, all of the same size, ten of which are grey and ten blue. How many socks must you pick up in order to make sure that you obtain a pair of the same colour? Over to you priscaoge,misbery...,olu...,yinkarh, and those who av guts. prof mizmycoli and benromeo am waiting o

benromeo39:
very simple, you have to pick at least 11. The first 10 could be the same color.

JayEye:
To ensure that they are of the same colour,

You simply pick three socks because a colour would appear twice and the other will appear once, thereby getting a pair of the same colour.


It will be three times.
It can't be two because you may pick two socks of different colours.
So its three socks.

despeakableme:
This is someone's mathematics assignment. Probability. U must pick 1 in order.

priscaoge:
Lol... My dear just pick 10socks each from the colors. Pick 10grey and 10blue and make sure they are ur size oooh

ogaofficer:
bros you wrong on the wrong path.

JayEye:


Well na the way i understand the english.
Abeg come drop your 'right path'.

Rephrase the question then.

franklyn009:

his answer is d most reasonable n logical answer to d question if u reason it from his point of view.
1. u said a dark cupboard: meaning u don't know which is grey or blue.
2. u said how socks must b picked in order to obtain 'a pair of sock': if I still know my English, a pair means 2 identical sock. therefore d maximum nô of sock to pick to obtain 'a pair' would b 3. which might b 2 blue n 1grey or 2 grey n 1 blue or 3 grey or 3 blue.


my opinion tho

JayEye:


Thank God someone is reasoning in my direction !

Wait, checking again ..the op is asking for pair of the same colors..that is four colours..two each of the same colour.

Zedric:
3. Since there are 2 colours if u pick 3 socks, there will definitely be 2 of the same colour

ogaofficer:
THE ANSWER IS four JAWE.

ogaofficer:
THE ANSWER IS four JAWE.

generalia:
you will have to pick all which is 20

ogaofficer:
TANKS BRO, those guys up there were the one confusing me, that was my first answer which i was expecting priscaoge to tell me by adding the 10+10 Together, bt immediately i saw A PAIR of the SAME COLOUR. then i arrived at four.

franklyn009:

the main ISH here is probably understanding the situation ( question).
can u do a little explanation here

JayEye:


Seriously??

You said four..

What if you pick
Blue
Blue
Blue
Grey

Where is the pair of the same colours then

ogaofficer:
blue blue grey grey

JayEye:


Your answer does not hold in all circumstance meaning its wrong.

You would have to pick five so as no matter the case, there is a pair of the same colours

ogaofficer:
hmmmn it seems i can begin to see what you are saying. But in other word by picking four am i not picking A PAIR OF THE SAME COLOUR OR AM PICKING A PAIR OF DIFFERENT COLOUR?

franklyn009:

its seem u too don't know d final answer.

I still stand on 3, cos d question said "a very dark cupboard" and all he wants is a pair of sock n he don't know wat colour of sock he would pick whenever he puts his hands in d cupboard...........so definitely after picking 3times, he must have a pair of sock.
