you spin the spinner once. what is p(not 7)? write your answer as a fraction or whole number.

Explanation:

Step1: Find total number of outcomes

There are 3 possible outcomes (5, 6, 7), so total = 3.

Step2: Find number of non - 7 outcomes

The non - 7 outcomes are 5 and 6, so number of non - 7 outcomes = 2.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{not }7)=\frac{2}{3}$.

Answer:

$\frac{2}{3}$
