1. Experimental and theoretical probability The spinner below shows equally sized slices ( grey, white, and black). Ashley spun the dial times and got the following results. Outcome Grey White Black Number of Spins Fill in the table below. Round your answers to the nearest thousandth. (a) One way to estimate the likelihood of an event is to repeat the experiment many times. The experimental probability of the event is the number of times the event occurs divided by the total number of trials of the experiment. In our problem, we get the following.

(b) Assuming that the spinner is fair means assuming that each slice is equally likely to be landed on. We use this to compute the theoretical probability. (We don't look at the data at all.)
