I believe the first one is A and B

A = { 3 } B = { 2, 4, 6, 8 }

So A and B = A ∩ B = { } (empty set )

For the second one

A... P (2 , 3 without replacement) = (2/13) * ( 1/12) = 2 / 156

B.....P ( 2, 5 without replacement) = (2/13) * (2/12) = 4 / 156

C...P( 3, 2 with replacement) = ( 1/13) * (2/13) = 2 / 169

D....P ( 5, 2 with replacement ) = (2/13) * ( 2/13) = 4 / 169

So......your answer is correct....!!!
