Question

what is p(not divisor of 28)? write your answer as a percentage. % submit

Explanation:

Step1: Find divisors of 28

Divisors of 28 are numbers that divide 28 without remainder. The divisors of 28 are 1, 2, 4, 7, 14, 28. From the spinner numbers (2,3,4,5,6,7,8,9), the divisors of 28 are 2,4,7. So non - divisors are 3,5,6,8,9.

Step2: Count total and non - divisor numbers

Total numbers on spinner: 8. Number of non - divisors: 5.

Step3: Calculate probability and convert to percentage

Probability \( P=\frac{\text{Number of non - divisors}}{\text{Total number}}=\frac{5}{8} \). To convert to percentage, \( \frac{5}{8}\times100 = 62.5\% \)

Answer:

62.5%
