you spin the spinner once. what is p(6 or prime)? write your answer as a fraction or whole number.
Answer
Explanation:
Step1: Identify prime numbers
The prime numbers on the spinner are 3, 5, 7.
Step2: Determine total outcomes
The total number of outcomes when spinning the spinner is 6 (the numbers 3, 4, 5, 6, 7, 8).
Step3: Find number of favorable outcomes
The numbers that are either 6 or prime are 3, 5, 6, 7. So there are 4 favorable outcomes.
Step4: Calculate probability
The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(6\text{ or prime})=\frac{4}{6}=\frac{2}{3}$.
Answer:
$\frac{2}{3}$
