Finding Complements. In Exercises 5鈥�8, find the indicated complements.

Flying In a Harris survey, adults were asked how often they typically travel on commercial flights, and it was found that PN=0.330, where N denotes a response of 鈥渘ever.鈥� What does PN炉represent, and what is its value?

Short Answer

Expert verified

PN炉represents the probability of a response other than 鈥渘ever.鈥� Its value is equal to 0.67.

Step by step solution

01

Given information

The probability of the response 鈥渘ever鈥� is denoted by and is equal to 0.330.

02

Express the Complementary events

Let E be an event. Then,E炉denotes all the outcomes that do not result in E.

In this case, E炉is called thecomplementary event of E.

The sum of the probabilities of E and its complement is equal to 1.

PE+PE炉=1

03

Compute the probability for the complementary event 

Let N be the event of getting a response of 鈥渘ever.鈥�

Then, N炉is the event of getting a response other than 鈥渘ever.鈥�

The probability of getting a response other than 鈥渘ever鈥� is calculated as follows:

PN炉=1-PN=1-0.330=0.670

Thus, PN炉is equal to 0.67.
