ok so probablity=(desired outcomes)/(total possible outcomes)
so total possible=7 siince 7 spaces
so example if you wanted to see the probablity of landing on the blue space then
desired outcomes=number of blue spaces=2
total possible=7
so probablity of landing on blue=2/7
2/7 means that if you spun it 7 times, you would land on blue 2 times
