Question

a. what are the possible values of the random variable x?
4, 5, 6, 7, 8
(use a comma to separate answers as needed.)
b. use random - variable notation to represent the event that the shuttle mission obtained has a crew size of 7.

Explanation:

Step1: Determine possible values of X

The random variable \(X\) represents the crew size. Looking at the context (assuming from a frequency - related table where crew sizes are 4,5,6,7,8), the possible values of \(X\) are the distinct crew - size numbers.

Step2: Represent the event using random - variable notation

If \(X\) is the random variable for crew size, and we want to represent the event that the crew size is 7, we use the notation \(X = 7\)

Answer:

a. \(4,5,6,7,8\)
b. \(X = 7\)
