Question

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?

Answer 1

There are five sectors.
Three sectors are green out of five sectors.
Therefore, probability of getting a green sector = $\frac{3 }{5}$
There is one blue sector out of five sectors.
Non-blue sectors = $5 – 1 = 4$ sectors
Therefore, probability of getting a non-blue sector = $\frac{4}{5}$
