Question

Use a spinner to find the theoretical probability of spinning an even number. What is the theoretical probability of spinning an even number?

(The spinner has 8 numbers)

Answer 1

1/2.

Explanation:

The even numbers from 1 to 8 are 2, 4, 6 and 8 so the probability of spinning an even number = 4/8 = 1/2.

Answer 2

4/8

Explanation:

There are half even and half odd numbers on a spinner so it is 1/2 of 8 which is 4. Then you put the 4 over 8 to gain your probability.
