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?

• A. Green $=\frac{1}{5}$, Non-Blue $=\frac{4}{5}$
• B. Green $=\frac{2}{5}$, Non-Blue $=\frac{1}{5}$
• C. Green $=\frac{3}{5}$, Non-Blue $=\frac{4}{5}$
• D. Green $=\frac{4}{5}$, Non-Blue $=\frac{1}{5}$

Answer 1

Answer: (C)

you have a spinning wheel with 3 green sectors, 1 blue sector and 1 red sector,is the probability of getting a Green sector $P\left(E\right)=\frac{Gree{n}_{sector}}{Tota{l}_{sector}}=\frac{3}{3+1+1}=\frac{3}{5}$

the probability of getting a Non-Blue sector $P\left(E\right)=\frac{non-Blu{e}_{sector}}{Tota{l}_{sector}}=\frac{1+1}{3+1+1}=\frac{3+1}{5}=\frac{4}{5}$
