If you have a spinning wheel with 3 green sectors, 1 blue sector and 1 red sector, what is the probability of getting a green sector? What is the probability of getting a non blue sector?

Total number of green sectors= 3

Total number of blue sectors= 1

Total number of red sectors= 1

Total number of sectors = $3+1+1=5$

Probability of getting a green sector= $\frac{Total number of green sectors}{Total number of sectors}$$=\frac{3}{5}$

Total number of non blue sectors= Total number of sectors - Total number of blue sectors = 5 - 1 = 4

Probability of getting a non blue sector= $\frac{Total number of non blue sectors}{Total number of sectors}=\frac{4}{5}$
