The probability of getting a 10 in the spinner is p(10) = 1/12.
How to find the probability?
We want to find the probability of getting a 10 in the spinner.
We can see that we have 12 equal sections, one of these sections has the number 10.
Then the probability of getting a particular value, is equal to the quotient between the number of times that we have that value in the spinner, and the total number of possible outcomes.
10 appears once
There are 12 outcomes:
Then:
P(10) = 1/12
