Write the symbols for the probability that of all the great hitters, a player is an outfielder.

Short Answer

Expert verified

The symbol indicating the likelihood that a player is an outfielder among all the great hitters is:P(O鈭�H)

Step by step solution

01

Given

The following information is provided in the given question:

There are infielders and outfielders on a baseball team. Some players are excellent hitters, while others are not so good.

02

Calculation

Let I represent a player who is an infielder.
Let O represent the possibility that a player is an outfielder.
Let H= be the case when a player is a fantastic hitter.
Let N represent the possibility that a guy isn't a particularly good hitter.
We need to create the symbol for the chance that a player is an outfielder out of all the outstanding batters.
Using the conditional probability event, the symbol for the likelihood that a player is an outfielder among all the great hitters is:

P(O鈭�H)

On February 28,2013, a Field Poll Survey reported that 61%of California registered voters approved of allowing two people of the same gender to marry and have regular marriage laws apply to them. Among 18to39year olds (California registered voters), the approval rating was 78%. Six in ten California registered voters said that the upcoming Supreme Court鈥檚 ruling about the constitutionality of California鈥檚 Proposition 8was either very or somewhat important to them. Out of those CA registered voters who support same-sex marriage, 75%say the ruling is important to them.

In this problem, let: 鈥�

C = California registered voters who support same-sex marriage. 鈥� B = California registered voters who say the Supreme Court鈥檚 ruling about the constitutionality of California鈥檚 Proposition 8 is very or somewhat important to them 鈥� A = California registered voters who are 18to39years old.

a. Find P(C).

b. Find P(B).

c. Find P(C|A).

d. Find P(B|C).

e. In words, what is C|A?

f. In words, what is B|C?

g. Find P(C AND B).

h. In words, what is C AND B?

i. Find P(C OR B).

j. Are C and B mutually exclusive events? Show why or why not
