Answer: d) 6,534,385

Therefore, the number of ways of selecting 9 hearts is 6,534,385

Step-by-step explanation:

Given;

Number of cards to be chosen = 12

Number of hearts to be chosen = 9

Number of non-hearts to be selected = 3

Total number of cards = 52

Number of hearts total = 13

Number of non-hearts total = 39

The number of ways of selecting hearts can be given by the illustration below.

Number of ways of selecting hearts * number of ways of selecting non-hearts

N = 13C9 * 39C3 (it's combination since order is not important)

N = 13! / (9! * 4!) * 39! / (36! * 3!)

N = 6,534,385

Therefore, the number of ways of selecting 9 hearts is 6,534,385
