**(1) **In a pack of 52 cards, there are 13 cards of heart. 2 cards of heart out of 13 cards of heart can be selected in ways.

∴ Total combinations = ^{13}C_{2} × ^{6}C_{3}

= \(\frac{13×12}{2}\)

= 20

**(2) **In a pack of 52 cards, there are 4 cards of king and 4 cards of queen one card of king out of 4 cards of king can be selected in ^{4}C_{1} ways and one card of queen out of 4 cards of queen can be selected In ^{4}C_{1} ways.

∴ Total combinations = ^{4}C_{1} × ^{4}C_{1}

= 4 × 4

= 16
