Question

1. use the spinner below to find p(not a 4). express your answer as a fraction.

Explanation:

Step1: Count total sections

The spinner has 12 equal - sized sections.

Step2: Count sections that are 4

There is 1 section labeled 4.

Step3: Calculate P(not 4)

The probability of an event not occurring is \(P(\text{not }A)=1 - P(A)\). Here, \(P(4)=\frac{1}{12}\), so \(P(\text{not }4)=1-\frac{1}{12}=\frac{12 - 1}{12}=\frac{11}{12}\).

Answer:

\(\frac{11}{12}\)
