Question 6. In a previous year, the weights of the members of the San Francisco 49ers and the Dallas Cowboys were published in the San Jose Mercury News. The factual data were compiled into the following table. Shirt# 1-33 21 34-66 6 66-99 6 210 211-250 5 18 12 251-290 0 7 22 > 290 0 4 5 For the following, suppose that you randomly select one player from the 49ers or Cowboys. a. Find the probability that his shirt number is from 1 to 33. b. Find the probability that he weighs at most 210 pounds. c. Find the probability that his shirt number is from 1 to 33 AND he weighs at most 210 pounds. d. Find the probability that his shirt number is from 1 to 33 OR he weighs at most 210 pounds. e. Find the probability that his shirt number is from 1 to 33 GIVEN that he weighs at most 210 pounds.

Answer Question 6

Question 5
People visiting video rental stores often rent more than one DVD at a time. The
probability distribution for DVD rentals per customer at Video To Go is given in the
following table. There is a five-video limit per customer at this store, so nobody ever
rents more than five DVDs.
a) Complete the Table
b) Determine the Expected value of rentals per customer and its standard
Deviation.
