Question

The spinner below is spun once. Find each probability as a percent rounded to the nearest whole number.

P(prime) =

%


P(odd and greater than 5) =

%

Answer 1

Answer: P(prime): 5/12 (.41667) P(odd and greater than 5): 3/12 (.25)

Explanation:

For the first probability, we can first identify the prime numbers on the wheel. Going around the wheel clockwise, the prime numbers here are: 2, 3, 5, 7, 11.

Since there are 12 total spaces on the wheel, the probability for P(prime) can be found by dividing the 5 prime numbers by 12 total spaces. Giving us 5/12.

For P(odd and greater than 5), similar to the first probability, we should first identify the numbers that follow the given rule. The numbers here that are odd and greater than 5 are: 7, 9, 11. Like the first probability, we divide the number of values here by the total spaces, giving us 3/12, or .25.
