Question

denote the crew size on a The following table displays a frequency distribution for the number of crew members on each shuttle mission over a 10-year period. Let randomly selected shuttle from this time period. Crew size 2 3 4 5 6 Frequency 2 5 40 22 6 a. What are the possible values of the random variable X? (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 5. c. Find P(X= 3). P(X = 3)= (Round to three decimal places as needed.) d. Obtain the probability distribution of X. 5 6 w X 2 4 P(X) (Round to three decimal places as needed.) e. Construct a probability histogram for X. Choose the correct histogram below. O A. OB OC. OD. Click to select your answer(s).

Answer 1

e) histogram A perfectly matches the distribution plot so , Option A is the correct answer .
