The student names are placed in a hat and 4 names are randomly drawn without replacement. a) If the first person drawn was named the class president, second person drawn was named vice president, third person drawn was named secretary, and the fourth person drawn was named treasurer how many different results would be possible?b) If the four names drawn constituted a committee, how many different committees would be possible? c) If the class of 30 students consisted of 14 men determine the probability that all four students randomly selected were men.
