Question

Can you please help me out with a question

Answer 1

37.5%

1) Examining the Spinner we can see that the total possibilities are:

90+45+90+135 = 360

2) Since the question is P(green or red) we can write out:

$\begin{gathered} P(g\text{ or r) = }\frac{90}{360}+\frac{45}{360}=\frac{135}{360}=0.375 \\ P(g\text{ or r) = P(g) +P(r) } \end{gathered}$

Note that the event of picking red or picking green can't exist simultaneously so they are mutually exclusive.

The result in percentage will be obtained by multiplying it by 100

3) Hence, the answer is 37.5%
