Question

Part A

Part B
What is the probability of green?​
A: 3/11
B:4/11
C:1/11
D:7/11

Answer 1

Since all sectors have the same area, the spinner is equaly likely to land on each of them. There are:

• 3 yellow sectors
• 3 red sectors
• 4 green sectors
• 1 blue sector

Obviously, this implies that there are 11 sectors in total.

So, the spinner will land on a certain color with probability

`p=\frac{\text{\# of sectors for that color}}{\text{11}}`

Use this formula to deduce the probability of green.

Finally, you can multiply the probability of red by 11 to get the expected number of reds in 11 spins.
