you spin the spinner once. what is p(greater than 7)? write your answer as a percentage. %
Answer
Explanation:
Step1: Identify favorable outcomes
The numbers greater than 7 on the spinner are 8. So there is 1 favorable outcome.
Step2: Identify total outcomes
The spinner has 4 sections numbered 5, 6, 7, 8. So there are 4 total outcomes.
Step3: Calculate probability
The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{greater than }7)=\frac{1}{4}$.
Step4: Convert to percentage
To convert a fraction to a percentage, we multiply by 100. $\frac{1}{4}\times100 = 25$.
Answer:
25%
