Suppose that nine Massachusetts athletes are scheduled to appear at a charity benefit. The nine are randomly chosen from eight volunteers from the Boston Celtics and four volunteers from the New England Patriots. We are interested in the number of Patriots picked. a. In words, define the random variable X.
b. List the values that X may take on.
c. Give the distribution of X. X ~ (,)
d. Are you choosing the nine athletes with or without replacement?

a) Random Variable - The value of this variable occur according to the frequency distribution

b) X may be volunteers from the Boston Celtics or the volunteer from New England Patriots

c) Distribution  1 to 13

d) Without replacement

Step-by-step explanation:

a) Random Variable - The value of this variable occur according to the frequency distribution

b) X may be volunteers from the Boston Celtics or the volunteer from New England Patriots

c) Distribution  1 to 13

d) Without replacement

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
