b. Number of possible poker hands with 2 hearts and 3 spades

When drawing 5 cards at random from a poker deck, the probability of drawing two Hearts and three Spades is

= 22308/2598960

= 0.008583433

2. Five students are to be sampled from a class of 30 students to form a committee consisting of a President, a Vice-President, a Secretary, a Treasurer, and a Councilor. This committee can be set up from the students of the class in the following number of ways:
