Question

The table shows a probability distribution P(X) for a discrete random variable X. What is P(X>2)?

Answer 1

0.30

Explanation:

You want P(x > 2) given the probability distribution table shown.

Greater than 2

There are two table entries where X > 2. One of them has a probability of 0.14, and the other a probability of 0.16. They are mutually exclusive, so the probabilities add.

P(x > 2) = P(x = 3) + P(x = 4) = 0.14 +0.16

P(x > 2) = 0.30
