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

[tex]P(A\cap B)=P(A)\cdot P(B)[/tex]

[tex]P(Q\cap R)=0.45\times 0.31=0.1395[/tex]

Answer:P( Q and R)=0.1395
