Answer 4

6. The formula for conditional Probability is: P(B|A) = P(A and B)/ P(A). Solve This formula for P(A and B).

Answer 5

nope, theres no image but some weird boxes at the end of it?

Answer 6

if you rearrange it, you'd make P(A and B) the subject

Answer 7

so by moving P(A) over to the other side, you'd get P(B|A) x P(A)

Answer 8

So you multiply P(A) on both sides?

Answer 9

And that's the answer? P(B|A) • P(A)?

Answer 10

yep which equals P(A and B)
