Chapter 10.6, Problem 44HP

To determine

To find: Explain to find the probability of an event by first calculating the probability of the complement of event.

Answer to Problem 44HP

Probability of an event is equal to subtracting from 1 the probability of an complementary event.

Explanation of Solution

Given Information: The given problem is about event and complement of an event.

Let us consider an event A

Then complement of event $A=A\text{'}$

The probability $=p(A\text{'})$

Probability of event A $P\left(A\right)=1-P(A\text{'})$

By subtracting from 1 the probability of an complementary event, we get probability of an event.
