Question 627778: There are 2500 students in a school. If I am wearing color A shirt then what is the probability that one of the other 2499 students is wearing the same color shirt.

I think the answer should be 1/2499 or maybe 1/7 raised to the power 2499 if we are talking about the seven primary colors.

There are only three primary colors.

Anyway, assuming there are seven colors with equal probability, the probability that at least one of the other 2499 students is wearing color A is equal to 1 - P(none of them wearing color A). This is equal to

, very close to 1.

If you are looking for the probability that *exactly* one is wearing color A, you have to use the binomial distribution.
