Short Answer

Expert verified

The given is a probability model.

Step by step solution

01

Step 1. Given information.

Determine whether the following is a probability model.

02

Step 2. Determine the probability model.

Analyzing the given table, the probability of each outcome are between 0 and 1.

Adding them together we have,

P1+P2+P3+P4=0.2+0.3+0.1+0.4=1

Since the probability of each outcome is between 0 and 1, and their sum is 1, then the given is a probability model.

03

Step 3. Conclusion.

The given is a probability model.
