Create table that gives cumulative probability distribution

Reference no: EM131416115

Suppose the probability distribution for X = number of jobs held during the past year for students at a school is as follows:

Number of jobs, X	0	1	2	3	4
Probability	.14	.37	.29	.15	.05

a. Find P(X ≤ 2), the probability that a randomly selected student held two or fewer jobs during the past year.

b. Find the probability that a randomly selected student held either one or two jobs during the past year.

c. Find P(X > 0), the probability that a randomly selected student held at least one job during the past year.

d. Create a table that gives the cumulative probability distribution for X.
