Question

you spin the spinner once. what is p(greater than 7)? write your answer as a percentage.

Explanation:

Step1: Identify total outcomes

The spinner has 4 sections numbered 6, 7, 8, 9. So the total number of possible outcomes is 4.

Step2: Identify favorable outcomes

The numbers greater than 7 on the spinner are 8 and 9. So the number of favorable outcomes is 2.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{greater than }7)=\frac{2}{4}=\frac{1}{2}$.

Step4: Convert to percentage

To convert a fraction to a percentage, we multiply by 100. So $\frac{1}{2}\times100 = 50\%$.

Answer:

50%
