Question

Suppose Q and R are independent events. Find P(Q and R). P(Q) = 0.87, P(R) = 0.51

Answer 1

0.4437

Explanation:

First we will define independent events.

Two events are said to be independent when the occurrence of one event doesn't affect the probability of occurrence of second event.

Given

P(Q)=0.87

and

P(R)=0.51

The probability of independent events is given as:

P(Q∩R)=P(Q)*P(R)

=0.87*0.51

=0.4437

So the probability of Q and R is 0.4437 ..
