Useing a common deck of cards, you are dealt a hand of 7 cards. Whis is the probability that all the different suits are present in your hand?
You've made a mistake. In combine(39,7) you don't have, necessarily, 3 suites presents.FrankEE2 said:...
The total number of unique 7 card hands that can be made from only 39 cards (3 suites present) would be combine(39,7), or 15,380,937. Since any of the 4 suites could be absent you would multiply that number by 4 to get 61,523,748.
