The outcome from tossing a coin is either heads (H) or tails (T). The tree
diagram shows all possible outcomes from tossing two coins.
A student defines event G as two heads that land face up after tossing
two coins, so G={HH} . Which list shows the complement of event G?
A.
{TT}
B.
{TH}, {HT}
C.
{TH}, {HT}, {TT}
D.
{TH}, {HT}, {TT}, {HH}

A.
B.

4. A single number cube numbered 1 to 6 is rolled twice. Event A is obtaining a 3 on the first roll
and event B is obtaining an even number on the second roll. Which of the following describes
these events?
A.
Events A and B are independent because the occurrence of one affects the occurrence of the other.
B.
Events A and B are dependent because the occurrence of one affects the occurrence of the other.
C.
Events A and B are independent because the occurrence of one does not affect the occurrence of the other.
D.
Events A and B are dependent because the occurrence of one does not affect the occurrence of the other.

7.
Amy rolled two six­sided number cubes. What is the probability (rounded
to the nearest hundredth) that the sum of the numbers on the cubes is a
prime number given that the number on the first cube is even?
A.
0.19
B.
0.39
C.
0.42
D.
0.50
8. Two events are described as follows:
Event A = a tossed quarter lands on heads
Event B = a cube numbered from 1 through 6 is rolled and lands with 7 on the top face
Which statement is true about the conditional probability,
that Event A will occur given
Event B has already occurred?
A.
The probability does not exist because the probability of Event B is zero.
B.
The probability is the probability of Event B since Event A occurs after Event B.
C.
The probability is the probability of Event A since Event B has no effect on Event A.
D.
The probability is the intersection of the probability of Event A and the probability of Event B.

The principal uses a computer to randomly select the name of a student from all the students in the
school. With the computer program, it is possible to draw the name of the same student twice. If the
principal selects the name of a student from the Blazers on the first try, what is the probability she will
draw the name of another student from the Blazers on the second try?
A.
B.
C.
D.
12.
Before the start of each football game, the players use a coin toss to
decide which team will get the football first. For the Tigers’ three
previous games, the coin toss resulted in tails landing face­up. A Tiger
player believes the next coin toss will result in heads, since tails has
already occurred the three previous times. Which statement best
describes the flaw in this player’s reasoning?
A.
Each coin toss is dependent on the previous coin toss.
B.
Each coin toss is independent of the previous coin toss.
C.
Since the coin has been tossed only three times, there are not
enough trials to reach a conclusion.
D.
Since the coin has landed on tails three times, the probability of
landing on tails again has increased.
