Chapter 5: Q 5.84. (page 216)

Suppose that A and B are events such that P(A)=0.84P(B)=0.46and P(A&D)=0.30Determine P(AorB).

Short Answer

Expert verified

P(A鈭�B)=0.92

Step by step solution

01

Step 1. Given information.  

P(A)=0.84P(B)=0.46P(A&B)=0.38

02

Step 2. Calculate the probability in the following manner.

P(A鈭�B)=P(A)+P(B)-P(A鈭�B)P(A鈭�B)=0.84+0.46-.0.38P(A鈭�B)=0.92

Occupations in Seoul. The population of Seoul was studied in an article by B. Lee and J. McDonald, "Determinants of Commuting Time and Distance for Seoul Residents: The Impact of Family Status on the Commuting of Women" (Urban Studies, Vol. 40, No. 7, pp. 1283-1302). The authors examined the different occupations for males and females in Seoul. The table at the top of the next page is a frequency distribution of occupation type for males taking part in a survey. (Note: M = manufacturing, N = nonmanufacturing.)

If one of these males is selected at random, find the probability that his occupation is

(a) service.

(b) administrative.

(c) manufacturing.

(d) not manufacturing.
