On February , a Field Poll Survey reported that of California registered voters approved of allowing two people of the same gender to marry and have regular marriage laws apply to them. Among year olds (California registered voters), the approval rating was . Six in ten California registered voters said that the upcoming Supreme Court’s ruling about the constitutionality of California’s Proposition was either very or somewhat important to them. Out of those CA registered voters who support same-sex marriage, say the ruling is important to them.
In this problem, let: •
C = California registered voters who support same-sex marriage. • B = California registered voters who say the Supreme Court’s ruling about the constitutionality of California’s Proposition 8 is very or somewhat important to them • A = California registered voters who are years 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
Use the following information to answer the next two exercises. You see a game at a local fair. You have to throw a dart at a color wheel. Each section on the color wheel is equal in area.
Let B = the event of landing on blue.
Let R = the event of landing on red.
Let G = the event of landing on green.
Let Y = the event of landing on yellow.
If you land on red, you don’t get a prize. What is P(R)?
At a college, of courses have final exams and of courses require research papers. Suppose that of courses have a research paper and a final exam. Let F be the event that a course has a final exam. Let R be the event that a course requires a research paper.
a. Find the probability that a course has a final exam or a research project.
b. Find the probability that a course has NEITHER of these two requirements.
