Chapter 5: Q 5.79. (page 216)

Suppose that A and B are mutually exclusive events such that P(A)=0.25andP(B)=0.40DetermineP(AorB).

Short Answer

Expert verified

As a result, P(AandB)has a value of0.65

Step by step solution

01

Step 1. Given information. 

P(A)=0.25P(B)=0.4

02

Step 2. P(A and B) is zero for mutually exclusive events.

The following formula is used to determine P(AandB):

P(AorB)=P(A)+P(B)0.25+0.4=0.65

As a result, P(AandB)has a value of0.65

In Exercises 5.16-5.26, express your probability answers as a decimal rounded to three places.

Graduate Science Students. According to Survey of Graduate Science Engineering Students and Postdoctorates, published by the U.S. National Science Foundation, the distribution of graduate science students in doctorate-granting institutions is as follows.

Frequencies are in thousands. Note: Earth sciences include atmospheric and ocean sciences as well.

A graduate science student who is attending a doctorate-granting institution is selected at random. Determine the probability that the field of the student obtained is

(a) psychology.

(b) physical or social science.

(c) not computer science.

U.S. Governors. In 2013, according to the National Governors Association, 30 of the 50 state governors were Republicans. Suppose that on each day of 2013, one U.S. state governor was randomly selected to read the invocation on a popular radio program. On approximately how many of those days should we expect that a Republican was chosen?
