LESSON 30 SESSION 1
➤ Complete problems 3-5.
3
A spinner has 5 equal-size sections numbered 1 through 5.
The spinner is spun one time.
a. Is it more likely that the spinner will land on an even number or
the number of getting
an odd number? Why?
an odd number
number, therefore greater than getting an even
Id number
b. How likely is it to spin a 1?
c. Why is it just as likely to spin a number greater than 3 as a number less than 3?
4 Use the spinner from problem 3.
a. What are the possible outcomes of spinning the spinner?
b. What are the possible outcomes for the event of spinning a prime number?
c. What are the possible outcomes for the event of spinning a factor of 4?
is likely that the Spinner will land on a
d. What are the possible outcomes for the event of spinning an even
number? An odd number?
