Solution Steps

Step 1: Verify the sum of the probabilities

The sum of the probabilities is: 0.288+0.522+0.146+0.039+0.004+0.001=1.000 0.288 + 0.522 + 0.146 + 0.039 + 0.004 + 0.001 = 1.000

Step 2: Check if each probability is between 0 and 1

Each probability is between 0 and 1, inclusive.

Final Answer

This is a discrete probability distribution because the sum of the probabilities is 1.000 and each probability is between 0 and 1, inclusive.
