A hand consists of six cards selected out of a stande 52card deck. [Assume that the cards are chosen simultaneously, so that the order does net matter and there is no replacement.) a. How many hands are possible? b. What is the probability that the hand contains exactly two of one kind and exactly three of another kind [but not four of a kind and not three of a kind for two separate kinds}? Recall that \"kind\" means ace, 2,3,...,10, jack, queen, king. For example, the condition is satised if you obtain two queens, three 5's, and an 8, but it is not satised if you obtain three queens and three 5's. It is also not satised if you obtain four queens and two 5's
