Suppose the probability distribution for X 5 number of jobs held during the past year for students at a school is as follows:
No. of Jobs, X 0 1 2 3 4
Probability .14 .37 .29 .15 .05
A. Find P(X . 0), the probability that a randomly selected student held at least one job during the past year.
B. Create a table that gives the cumulative probability distribution for X.
