Chapter 12: Q27. (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(red, white, white).

Short Answer

Expert verified

The required probability is 22325.

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(red, red, red).

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

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

First chip: P(red)=826

Second chip: P (white)=1225

Third chip: P (white)=1124

P (red, white, white)=826脳1225脳1124=22325

Therefore the required probability is 22325.
