Write the symbols for the probability that of all the outfielders, a player is not a great hitter.
A student goes to the library. Let events B = the student checks out a book and D = the student checks out a DVD. Suppose that P(B) = 0.40, P(D) = 0.30 and P(D|B) = 0.5.
a. Find P(B′).
b. Find P(D AND B).
c. Find P(B|D).
d. Find P(D AND B′).
e. Find P(D|B′).
Use the following information to answer the next six exercises. There are 23 countries in North America, 12 countries in South America, 47 countries in Europe, 44 countries in Asia, 54 countries in Africa, and 14 in Oceania (Pacific Ocean
region).
Let A = the event that a country is in Asia.
Let E = the event that a country is in Europe.
Let F = the event that a country is in Africa.
Let N = the event that a country is in North America.
Let O = the event that a country is in Oceania.
Let S = the event that a country is in South America.
Find P(N).
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)
