Chapter 13: Q. 9 (page 864)

Determine whether the following is a probability model.

Short Answer

Expert verified

The given is not 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,

PLinda+PJean+PGrant+PJim=0.3+0.2+0.1+0.3=0.9

Although the probability of each outcome is between 0 and 1, their sum is not equal to 1.

Thus the given is not a probability model.

03

Step 3. Conclusion. 

The given is not a probability model.
