Question

If the probability of an event is 0.39 what is the probability of its complement

Answer 1

let the probability of the event be P(A)=0.39

so the probability of its complement is

=1-P(A)

=1- 0.39

=0.61

Answer 2

The probability of its complement is 0.61.

Step-by-step explanation:

Given : If the probability of an event is 0.39.

To find : What is the probability of its complement ?

Solution :

Let the probability of an event is P(A)=0.39.

The compliment of event is P(A') is given by,

$P(A')=1-P(A)$

Substitute the value,

$P(A')=1-0.39$

$P(A')=0.61$

Therefore, the probability of its complement is 0.61.
