you spin the spinner once. what is p(not prime)? write your answer as a percentage rounded to the nearest tenth. %
Answer
Explanation:
Step1: Identify prime and non - prime numbers
Prime numbers among 2, 3, 4, 5, 6, 7, 8, 9 are 2, 3, 5, 7. Non - prime numbers are 4, 6, 8, 9.
Step2: Calculate total and non - prime numbers
Total numbers on spinner = 8. Number of non - prime numbers = 4.
Step3: Calculate probability
$P(\text{not prime})=\frac{\text{Number of non - prime numbers}}{\text{Total numbers}}=\frac{4}{8}=0.5$
Step4: Convert to percentage
$0.5\times100 = 50.0%$
Answer:
$50.0%$
