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
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.
