A_2 = 8 * (x + 5)

A_1 = A_2

7(x + 7) = 8(x + 5)

If A and B are independent events, P(A) = 0.4, and P(B) = 0.5, what is P(BIA)?
pantera1 [17]

Answer:

answer A. 0.5

Step-by-step explanation:

hello

as A and B are independent P(B/A)=P(B) =0.5

in short, the information provided by the event A does not impact at all the event B. so knowing A or not does not impact the probability of B.

you can use the formula as well P(B/A)=P(A and B) / P(A)=(P(A)xP(B))/P(A)=P(B)

hope this helps
