Chapter 3: Q.43 (page 217)

Q and R are independent events. P(Q)=0.4 and P(QANDR)=0.1. Find P(R).

Short Answer

Expert verified

P(R)=0.25

Step by step solution

01

Content Introduction

Independent event are ones whose event is not contingent on the occurrence of another event.

02

Content Explanation

It is given that Q and R are independent events.

Therefore, P(R) can be calculated as follow:

P(Q AND R)=P(Q)×P(R)0.1=0.4×P(R)P(R)=0.25

Fifty percent of the workers at a factory work a second job, 25% have a spouse who also works, 5% work a second job and have a spouse who also works. Draw a Venn diagram showing the relationships. Let W = works a second job and S = spouse also works.

Use the following information to answer the next ten exercises. Forty-eight percent of all Californians registered voters prefer life in prison without parole over the death penalty for a person convicted of first degree murder. Among Latino California registered voters, 55%prefer life in prison without parole over the death penalty for a person convicted of first degree murder. 37.6% of all Californians are Latino. In this problem, let: • C = Californians (registered voters) preferring life in prison without parole over the death penalty for a person convicted of first degree murder. L = Latino Californians. Suppose that one Californian is randomly selected.

Find P(C).
