## Coin Toss

#### Activity Overview

Students will run two experiments that simulate pouring out coins from a bag.

#### Key Steps

• In the first experiment, a program models pouring coins out of a bag. Each time the coins are poured out, the ones that land heads up are removed and the remaining ones are shaken and poured out again until they are gone.

• Students will collect the data and find the ratio of the number of coins by dividing the 2nd term in the number of coins list by the 1st term. They will also calculate the mean of the ratios.

• Students will use different methods to find equations to model the data.
