Part A
If you spin the spinner 11 times, what is the prediction for the number of times it will land on red?


Each section is equal in size.(it's talking about the spiner)




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

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

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

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

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.
