A teacher was on a committee consisting of four male and two female teachers. Two members of the committee were chosen to do some extra work, and it turned out that both females were chosen. The teacher wondered how likely this result would have been if the selection (of two people to do the extra work) had been made at random (from among the six committee members). 

a. Describe how you could use index cards to conduct a simulation analysis to approximate the probability that the teacher is interested in. 

b. Would it work to simulate this random process by rolling a pair of six-sided dice and using the numbers rolled to represent the people selected? Explain why or why not.
