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

Explanation:

Step1: Find total number of outcomes

The spinner has 4 sections, so the total number of possible outcomes is 4.

Step2: Find number of non - 4 outcomes

The non - 4 outcomes are 7, 6, 5, so there are 3 non - 4 outcomes.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{not }4)=\frac{3}{4}$.

Step4: Convert to percentage

To convert a fraction to a percentage, we multiply by 100. $\frac{3}{4}\times100 = 75%$.

Answer:

75%
