Chapter 13: Q. 12 (page 865)

In Problems 11鈥�16, construct a probability model for each experiment.

Tossing two fair coins once.

Short Answer

Expert verified

The list of possible outcomes: S=HH,HT,TH,TT.

The probability of each outcome:PHH=14,PHT=14,PTH=14,PTT=14

Step by step solution

01

Step 1. Given information.

Construct a probability model for experiment: Tossing two fair coins once.

02

Step 2. Construct probability model.

Considering the following outcomes for each toss:

First coin - A head (H) or a tail (T), Second coin - A head (H) or A tail (T) .

The list of possible outcomes in tossing two coins once will be:

S=HH,HT,TH,TT

The probability of each outcome will be:PHH=14,PHT=14,PTH=14,PTT=14

03

Step 3. Conclusion. 

The list of possible outcomes: S=HH,HT,TH,TT.

The probability of each outcome:PHH=14,PHT=14,PTH=14,PTT=14.
