Question

you spin the spinner once. what is p(not 4)? write your answer as a percentage rounded to the nearest tenth.

Explanation:

Step1: Count total outcomes

There are 5 sections on the spinner, so the total number of possible outcomes is 5.

Step2: Count non - 4 outcomes

The non - 4 outcomes are 1, 2, 3, 5, so there are 4 non - 4 outcomes.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{not }4)=\frac{4}{5}$.

Step4: Convert to percentage

To convert $\frac{4}{5}$ to a percentage, we do $\frac{4}{5}\times100\% = 80.0\%$.

Answer:

80.0%
