Binomial Distribution · Exercise 15
A school newspaper reporter decides to randomly survey 12 students to see if they will attend Tet (Vietnamese New Year) festivities this year. Based on past years, she knows that 18% of students attend Tet festivities. We are interested in the number of students who will attend the festivities.
(a) In words, define the random variable X.
(b) List the values that X may take on.

(f) Find the probability that more than two students will attend.
