you spin the spinner once. what is p(not factor of 25)? write your answer as a fraction or whole number.

Answer:

$\frac{5}{8}$

Explanation:

Step1: Find factors of 25

The factors of 25 are 1, 5, 25. Among the numbers on the spinner (1 - 8), the factors of 25 are 1 and 5.

Step2: Calculate number of non - factors

There are 8 numbers on the spinner. The number of factors of 25 on the spinner is 2. So the number of non - factors is $8 - 2=6$.

Step3: Calculate probability

The probability $P(\text{not factor of }25)=\frac{\text{number of non - factors}}{\text{total number of outcomes}}=\frac{6}{8}=\frac{3}{4}$
