Chapter 12: Q28. (page 796)

A box contains 8 red chips, 6 blue chips, and 12 white chips. Three chips are randomly drawn from the box and are not replaced.

Determine P(blue, blue).

Short Answer

Expert verified

The required probability is 365.

Step by step solution

01

Step 1. Define the meaning of probability.

The probability is a measure of the likelihood of an event to occur.

02

Step 2. Define the meaning of random event.

A random event is an event whose outcome is unpredictable.

03

Step 3. Determine the probability P(blue, blue).

Since, the three chips are randomly drawn from the box and are not replaced.

To determine the probability, choose one chip from blue chips and one chip from blue chips.

First chip: P(blue)=626

Second chip: P (blue)=525

P (blue, blue)=626脳525=365

Therefore the required probability is 365.
