jackpot:
when a random experiment gave me 85 without birthday mates (and 15 with birthday mates) out of 100

If anything, the two are not close. Random experiments often give clue to magnitude of the answer.

Try and run the experiment with a section of the players data. It helps to appreciate results when they come.

But you may use a consecutive 100 players for the experiment to have semblance of randomness

Thanks for the clarification.
This is my points exactly.
Based on this example, 15 people have shared birthdays but the number of shared birthdays is just 7. That's the difference I was talking about.

The question requires.... Number of unshared birthdays from the group and not number of students with an unshared birthday.

jackpot:
my question is different from the birthday paradox. Birthday paradox has it's origin in the probability of at least a member of a group of size k (an integer>2) having a birthday mate.

But birthday paradox helps a bit to understand the question.

If the probability that a member of a group having a birthday mate in a group of 100 is 99.99997%, one can infer that on average those that have birthday mate(s) in a random group of 100 are a significant number x.

I'm looking for (100-x) being number of those that don't have birthday mates.

naturalwaves:
You've not answered my question. From the 15 people with shared birthdays, how many birthdays are shared
15 people can share just 1 birthday.

jackpot:
His answer is correct but I think it is not the direct answer to the question I posed.

jackpot:
I think that you are solving a different question

The question says expected number of unshared birthdays among 100 students?

Loris576:
My brother ..i think the question is not complete

Martinez39s:
You are correct! The answer is M = (2n + 1)180°, where n is any integer. MrShape got this result, but he added 0° to his solution. Please show your working.

Martinez39s:
Wrong! You are almost there. You are nearer to the answer than before.

NB: I have my workings, and I will post my solution tomorrow.

Martinez39s:
WRONG! You are almost there. M = 360° wouldn't work (try A = 150°, B = 75°, and C = 135° as a test.)

Guiddoti, won't you attempt the question.

franklingud:
Fvck I hate maths!!

I don't know sh!t about maths.

Just think of it, how and where did M get into that equation?

I thought it was going in alphabetical order.

franklingud:
it started with A, B and C, Where and how did M come into this equation??

It should have been D not M.


I hate maths

Due of immense boredom, I decided to compose this simple question for Nairaland mathematicians:

Na wa for people we call Graduates this days... he said he wants to give a telivised broadcast by 8pm.. at no point did he call it a live broadcast and at no point did he call it a live session without pre written speech... Femi Adesina was the first to post the speech on his page, as i believe he must had written it unbehalf of Mr President.. almost all world leaders have speech writters and read speeches from telepromters or paper, unlike few cases of Donald Trump where he keeps embarrassing the US with his unreharsed on prepared daily speech sugesting hydrochloroquine, or Disinfectant to his citizen without any sense of safety

Stephenomozzy:
Lol... Sold cow to take another cow to school. Mad!

Maybe I might be Phoenix.

Answer na: 22

40 divided by the half of itself = 40/20 = 2

Now add 20 = 20 + 2 = 22

Assuming say you nor want make we con still dey use simultaneous equations

Nope...that's not correct sir

I have Noticed that in Mathematics, Any problem comes with either Looking for X, Solve for X, Dy/Dx, solve for X, Y and Z

What Happened to other Alphabets?
Is there anything special about X, Y and Z
Especially "X"

Assume the market for bread originally could be described as being in equilibrium and that the market is working in accordance to the basic model for a market. At the market for bread two disturbances affecting the market occurs at the same time. The first disturbance is that crops of grains, used for making bread, becomes exceptionally large. The second disturbance is that the population chooses to consume more of other types of food than bread. Consumers choose to consume more of vegetables and fish instead of bread. Use the market model and describe what consequences you could expect on the bread market (prices and quantities) from these two disturbances. What conclusions can you be sure of and what conclusions are unsure? Motivate your answer and use diagrams.



Please who can solve this?.. Incentive dey.. Even though it's small

mtn?

I created this thread because I am so bored and I need to just chill here. However, it is pretty obvious that people may not engage if there's no incentives, and it's going to be a whole lot interesting that way, so I am going to give 100 to three people who answer five questions correctly. Sorry it's just 300. I am not financially stable, maybe later sha. If you answer five of your ten questions I'd ask you any subject, then you'll get paid
Ask from maths

Now to the topic, I am going ask you questions on just about anything under the sun on what I already know at this point of my miserable life, not something googled OR researched at the moment.

Likewise, and please, please for the love of God, don't research or google search these questions. It has to be something you already know. If you don't know it, you can just request another question.

It's going to be on an individualistic basis. Drop a comment so I can start with you.

Ciao.
