What you’ll practice

Restrict the sample space to the event after the conditioning bar. This can change a probability even though the original events have not changed.

Where this helps

Working with a restricted sample space.

Before you start

Use this topic to practice math you have already learned. The examples show the available kinds of recall tasks; this is not a complete textbook chapter. Check the answer form and any stated conditions.

Try a few examples

Real practice. Real progress.

Example 1 of 1

All events share one probability space and P(B) is strictly positive.

Choose the exact expression.
