**The United States Senate: Probability and Statistics**

The United States Senate consists of 100 members. Suppose that there are 54 Republicans and 46 Democrats. When a committee of 15 members is selected at random, statistical calculations can determine the expected number and standard deviation of Republicans in this committee.

**Question 1: Expected Number of Republicans**

- The expected number of Republicans on this committee is 8.1.

- This figure is marked with a green check, indicating it is correct.

**Question 2: Standard Deviation of Republicans**

- The standard deviation of the number of Republicans on this committee is 3.726.

- This answer is marked with a red cross, indicating it is incorrect.

These computations involve principles of probability and statistics, which can be used to analyze selections in large groups with known proportions.
