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

total number of black card =26

total number of  red cad without face card=20(26-6)

hence,probability of finding non black card along with face card =20C2/52 C 2
