1. The sample space S is the whole numbers starting at one and less than 20.
a. S =
Let A = the even numbers, Let B= numbers greater than 13.
b. A = B =
c. P(A) = P(B) =
d. A AND B= P(A AND B) =
e. A OR B= P(A OR B) =
f. A′= P(A′) =
g. P(A) +P(A′) =
h. A GIVEN B P(A|B) =
i. B GIVEN A P(B|A) =
2. A box is filled with several party favors. It contains 12 hats, 15 noisemakers, 10 finger traps,
and 5 bags of confetti.
• Let H = the event of getting a hat.
• Let N = the event of getting a noisemaker.
• Let F = the event of getting a finger trap.
• Let C = the event of getting a bag of confetti.
a. P(H) =
b. P(N OR F) =
c. P(C’) =
3. You are rolling a fair, six-sided number cube. Let E = the event that it lands on an even number. Let M = the event that it lands on a multiple of three.
a. What does P(E|M) mean in words?
b. What does P(E OR M) mean in words?
4. What is the sum of the probabilities of an event and its complement?
5. What is the probability of drawing a club in a standard deck of 52 cards?
6. What is the probability of rolling a prime number of dots with a fair, six-sided die numbered
one through six?
