Chapter 5: Q. 106. (page 337)

If P(A) = 0.24, P(B) = 0.52, and A and B are independent events, what is P(A or B)?

a. 0.1248

b. 0.28

c. 0.6352

d. 0.76

e. The answer cannot be determined from the information given.

Short Answer

Expert verified

The required answer is 0.6352

The correct option is(c)

Step by step solution

01

Given information

P(A)=0.24,P(B)=0.52,Aand Bare independent.

02

Explanation

Because Aand Bare separate events,

PAa^鈭�aB=p(A)P(B)=0.24(0.52)=0.1248PAa^鈭�B=P(A)+P(B)-P础芒鈭�鈯�B=0.24+0.52-0.1248=0.6352

Therefore, the option (c)is correct.

Reading the paper In a large business hotel, 40% of guests read the Los Angeles Times. Only 25% read the Wall Street Journal. Five percent of guests read both papers. Suppose we select a hotel guest at random and record which of the two papers the person reads, if either. What鈥檚 the probability that the person reads the Los Angeles Times or the Wall Street Journal?

a. Make a Venn diagram to display the outcomes of this chance process using events L:reads the Los Angeles Times and W: reads the Wall Street Journal.

b. Find PLC鈭�W.
