statistics probability

Question

Use the spinner below to find the probability of getting the following number after 1 spin.

P(3 or 2) = rrect   (Please enter a reduced fraction)

Answer 1

The chance on landing on any number is 1/12, since there are 12 numbers on the spinner.

So the chance of landing on a 2 is 1/12 and the chance of landing on a 3 is 1/12.

These must be added to find the total probability of landing on a 2 or 3.

1/12 + 1/12 = 2/12 simplify and you get 1/6
