I am not wrong then the number of face cards (12) plus black cards (13) combined is 22. Then two cases arise with replacement or without replacement for
1st case that is with replacement:-
p = (22/52)*(22/52) = 121/676
2nd case without replacement:-
p = (22/52)*(21/51) = 77/442
So i guess the answer given bye you is wrong ,, please correct me if i am wrong or you need any further clarification
