-Given that 75,511 out of 822,959 residents enrolled in the college, the probability of success is calculated as:
#We know that this is a binomial distribution with p=0.09176 and n=800, Expected value is calculated as:
Hence the expected value E(X)=73.4
There are exactly 15 remainders modulo 15 and they are 0,1,2,…,14.
It is given that at least two of them should have the same remainder when divided by 15.
Division algorithm.
Let aa be an integer and d a positive integer. Then there are unique integers q and r with such that
q is called the quotient and r is called the remainder
q=a div d
r=a mod d
Pigeonhole principle If k is a positive integer and k+1or more objects are placed into k boxes, then there is at least one box containing two or more objects.
Hence, there are exactly 15 remainders modulo 15 and they are 0,1,2,…,14.
