Question

Events A and B are independent.

P(A and B)=0.25

Enter possible possibilities for events A and B.

P(A)=

P(B)=

Answer 1

P(A)=0.5

P(B)=0.5

Explanation:

It's known that P(A and B) = P(A) * P(B) "When A and B are independent.

Now, suppose that P(A) = P(B)

then

P(A) * P(B) = P(A) * P(A) = (P(A))^2

finally

(P(A))^2 = 0.25

`P(A) = √(0.25)`
