1. The spinner has 8 equal sections. What is the probability that it lands on purple?

1. 5/8

There are 8 equal sections, so there are 8 equally likely outcomes.

5 of the sections are purple.

P(purple) = 5/8.

2. 1/5

There are 10 equal sections, so there are 10 equally likely outcomes.

2 of the sections are red.

P(red) = 2/10 = 1/5.

3. 9/10

There are 10 equal sections, so there are 10 equally likely outcomes.

9 of the sections are purple.

P(purple) = 9/10.

4. 2/3

There are 6 equal sections, so there are 6 equally likely outcomes.

4 of the sections are green.

P(green) = 4/6 = 2/3.

5. 1/4

There are 4 equal sections, so there are 4 equally likely outcomes.

1 of the sections is red.

P(red) = 1/4.
