compound event
6
A compound event consists of two or more single
events. For example, the birth of one child is a
single event. The births of four children make up
a compound event.

Additional Example 1A Finding Probabilities of
Compound Events Jerome spins the spinner
and rolls a fair number
cube. A. Find the probability that the
number cube will show an even number and
that the spinner will show a B.
8
Additional Example 1A Continued
First find all of the possible outcomes.
Number Cube
Spinner
There are 18 possible outcomes, and all are
equally likely.
Three of the outcomes have an even number and B
2, B 4, B and 6, B.

Additional Example 1B Finding Probabilities of
Compound Events B. Find the probability that the
number cube will show a 4 and that the spinner
will show an A.
Only one outcome is 4, A.
11
Additional Example 1C Finding Probabilities of
Compound Events C. In the experiment on page
575, what is the probability that the coin will
show tails, the spinner will land on purple, and
a green marble will be chosen?
There are 18 equally likely outcomes.

rolls a fair number cube.
A. Find the probability that the number cube will
show an odd number and that the spinner will show
an A.

Lesson Quiz
An experiment involves one spin
of the spinner and one flip of the
coin. Find each probability. 1. What
is the probability of the spinner landing on red
and the coin landing tails up? 2. What is the
probability of the spinner landing on an odd
number and the coin landing heads up? 3. What is
the probability of the spinner landing on an even
number and the coin landing tails up?
