Question

Suppose Q and R are independent events. Find P(Q and R) if P(Q) = 0.32 and P(R) = 0.19.

Answer 1

.32*.19=0.608
Sinc3 they are independent

Answer 2

ANSWER


`P(Q \: and \: R)=0.0608`


It was given that,


`P(Q) = 0.32`
and


`P(R) = 0.19`



Events Q and R and independent events if and only if




`P(Q \: and \: R)=P(Q) * P(R)`


We therefore substitute the respective probabilities to obtain,



`P(Q \: and \: R) = 0.32*0.19`


`P(Q \: and \: R)=0.0608`
