For a low number of coin tosses, the actual distribution may differ much or little from what is expected depending on random chance. For a high number of tosses, however, the distribution will be what is expected. |

Discussion:
The probability of an event occurring is # of desired outcomes that can occur divided by the total # of outcomes possible.
