# Geometry

Hi, I have a Benchmark test tomorrow and I don't understand how to calculate the probability of this problem. A fair coin is tossed and the spinner is spun. All outcomes on the spinner is equally likely. Find the probability of getting heads or landing on C.

1. 0
2. 0
3. 6
1. coin outcomes are 1/2 each

If the spinner has n areas, then each has a 1/n chance of being hit

So, P(H,C) = 1/2 * 1/n
