Graph the results of a coin toss:

Toss Coins

0 20

1 12

2 5

3 1

4 0

State an equation that best fits the results (use n to represent the number of the toss). What physical phenomenon does this model?

I was able to graph this, I just do not understand how to write the equation, or what it models???
