Question

a spinner with repeated colors numbered from 1 to 8 is shown. sections 1 and 8 are purple. sections 2 and 3 are yellow. sections 4, 5, and 6 are blue. section 7 is orange. determine p(not blue) if the spinner is spun once. o 12.5% o 25% o 37.5% o 62.5%

Explanation:

Step1: Count total sections

The spinner has 8 sections.

Step2: Count non - blue sections

Sections 1, 2, 3, 7, 8 are non - blue. There are 5 non - blue sections.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{not blue})=\frac{5}{8}$.

Step4: Convert to percentage

$\frac{5}{8}=0.625$, and $0.625\times100\% = 62.5\%$.

Answer:

62.5%
