There are 13 hearts and we are to choose 5. That's 13 choose 5 or 13C5 = 1287
There are 4 jacks and we are to choose 3 That's 4 choose 3 or 4C3 = 4 For each of those 4 ways to select the jacks, there are 4 sevens and we are to choose 2 That's 4 choose 2 or 4C2 = 6 We multiply those and get 4*6 = 24 ways. Edwin
