Let y be a binomial random variable with parameters n and p. what is the probability that y is n? choose the correct answer below. a. (1 minus p )superscript n b. p superscript n c. np(1-p)^2 d. (np)^2 e. (1-p)^2

answer: a.   one is a factor of every whole number since every number is divisible by itself.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
