# Question: Use the probability mass function

Use the probability mass function in Exercise 3-11 to determine the following probabilities:

(a) P (X < 2)

(b) P (0.5 < X < 2.7)

(c) P (X > 3)

(d) P (0 < X < 2)

(e) P (X = 0 or X = 2)

Verify that the following functions are probability mass functions, and determine the requested probabilities.

(a) P (X < 2)

(b) P (0.5 < X < 2.7)

(c) P (X > 3)

(d) P (0 < X < 2)

(e) P (X = 0 or X = 2)

Verify that the following functions are probability mass functions, and determine the requested probabilities.
