Answer #1

Sample space contains 8 people.

Let X = number of people who have a college degree.

Then X can takes the values 0,1,2,3,4,5,6,7 and 8. Zero corresponding to no one has college degree, ... , 8 corresponding to all of the eight people have college degree.

Therefore possible values of the random variable X are 0,1,2,3,4,5,6,7 and 8.

    8. Exercise: Counting committees Bookmark this page Exercise: Counting committees 0.0/2.0 points (graded) We start with a pool of n people. A chaired committee consists of k 1 members, out of whom one member is designated as the chairperson. The expression k(can be interpreted as the number of possible chaired committees with k members. This is because we have choices for the k members, and once the members are chosen, there are then k choices for the chairperson. Thus, is...

    In a survey of 1000 eligible voters selected at random, it was found that 200 had a college degree. Additionally, it was found that 90% of those who had a college degree voted in the last presidential election, whereas 46% of the people who did not have a college degree voted in the last presidential election. Assuming that the poll is representative of all eligible voters, find the probability that an eligible voter selected at random will have the following...

    Suppose that we go sequentially through a group of people asking each in turn to pick one of 5 options (e.g., "rock," "paper," "scissors," "fire," or "water") at random. Let Xi (for 0 ? i ? 4) be the random variable giving the number of additional people we have to ask before getting an option that has not been picked yet. (So X0 is the number of people we have to ask to get the first option, which will be...
