Question

Suppose Q and R are independent events, and P(Q) = 0.45, P(R) = 0.31. Find P(Q and R).

Answer 1

The right anser is A: 0.1395 because you multiply the two possibilities. 

Answer 2

Answer:

0.1395

Step-by-step explanation:

We are given that Q and R are independent events.

P(Q)=0.45

P(R)=0.31

We have to find the value of P(Q and R).

We know that when two events are independent then

$P(A\cap B)=P(A)\cdot P(B)$

$P(Q\cap R)=0.45\times 0.31=0.1395$

Answer:P( Q and R)=0.1395
