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....!!!

Thank you so much for your help! I didn't think that I had either question correct.
