you spin the spinner once. what is p(not 4)? write your answer as a fraction or whole number.

Explanation:

Step1: Determine total outcomes

There are 3 possible outcomes (3, 4, 5).

Step2: Determine non - 4 outcomes

The non - 4 outcomes are 2 (3 and 5).

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{not }4)=\frac{2}{3}$.

Answer:

$\frac{2}{3}$
