The investigators explored marijuana use among eighth grade students. The following table presents findings of response to the question "Smoked marijuana ever?"

Problem 1: Three students are randomly selected with replacement from the data set. What is the probability that the first two students never smoked marijuana and the third student did?

Define the events as follows:

E1 = The first student never smoked marijuana

E2 = The second student never smoked marijuana

E3 = The third student did smoke marijuana

Problem 2: What is the probability that exactly two of the three students never smoked marijuana? We define the events as follows:

F = Only the third student of three smoked marijuana.

G = Only the second student of three smoked marijuana.

H = Only the first student of three smoked marijuana.
