A jar of 150 jelly beans contains 22 red jelly beans, 38
yellow, 20 green, 28 purple, 26 blue, and the rest are orange.
Let B = the event of getting a blue jelly bean
Let G = the event of getting a green jelly bean.
Let O = the event of getting an orange jelly bean.
Let P = the event of getting a purple jelly bean.
Let R = the event of getting a red jelly bean.
Let Y = the event of getting a yellow jelly bean.
Find P(B).
The following table of data obtained from www.baseball-almanac.com shows hit information for four players. Suppose that one hit from the table is randomly selected.
Are "the hit being made by Hank Aaron" and "the hit being a double" independent events?
a. Yes, because P(hit by Hank Aaron | hit is a double) P(hit by Hank Aaron)
b. No, because P(hit by Hank Aaron | hit is a double) P(hit is a double)
c. No, because P(hit is by Hank Aaron | hit is a double) P(hit by Hank Aaron)
d. Yes, because P(hit is by Hank Aaron | hit is a double) P(hit is a double)
