The following table displays a frequency distribution for the number of crew members on each shuttle mission from April 12, 1981 to July 8, 2011.

Let
C
= Crew Size

a) How many shuttle missions were there from April 12^th, 1981 to July 8, 2011?

b) Create a probability distribution for the random variable
C

Use your probability distribution to find:

c) P(C
= 6) =

d) P(C
is at least 4) =

e) P(C
is no more than 7) =

f) P (4 ≤
C
≤ 7) =

g) P (2
C
≤ 5) =

h) What is the expected crew size? E(C) =
