Answer:
yes, event A and B independent
Step-by-step explanation:
given data
P(A) = 0.25
P(B) = 0.60
P(A and B) = 0.15
solution
we know here P(A and B) = 0.15
so we know here for independent
P(A and B) is = P(A) × P(B) .......................1
so we take here R.H.S here in equation 1 and put here value
P(A) × P(B)
P(A) × P(B) = 0.25 × 0.60
P(A) × P(B) = 0.15
so it is equal to L.H.S = R.H.S
so, we can say that A and B are independent
Answer:
1/4
