X = the number of students who get a random number greater than 0.9.

(a) What is the distribution of X? That is, give the name and parameter values of the

distribution or write down the probability mass function.

(b) What is the expected number of students who get a random number greater than 0.9?

(c) What is the probability that 3 or less students get a random number greater than 0.9?
