Question

sule will spin this spinner once.
what is the probability that she will not spin a 4?
1/6 5/6 1/8 7/8

Explanation:

Step1: Find total number of outcomes

The spinner has 6 sections. So total number of outcomes \(n = 6\).

Step2: Find number of non - 4 outcomes

The number of sections that are not 4 is \(n(\text{not }4)=5\) (sections with 3,5,6,7,8).

Step3: Use probability formula

The probability formula is \(P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). For the event of not spinning a 4, \(P(\text{not }4)=\frac{5}{6}\).

Answer:

\(\frac{5}{6}\)
