#### Worksheet Overview

If you flipped a coin 100 times, how many times would you expect it to land on tails?

This activity is going to focus on estimating the number of times we expect something to happen.

To do this we can multiply its probability by the number of trials.

For example, if a six-sided die is rolled 240 times (240 trials) we would expect it to land on each number 40 times (1/6 x 240 = 40)
