probabillity that number of heads in trial is_ | 0 | __=__ | 4 / 80 | __=__ | 0.05 |

probability that number of heads in trial is | 1 | = | 8 / 80 | = | 0.10 |

probability that number of heads in trial is | 2 | = | 36 / 80 | = | 0.45 |

probability that number of heads in trial is | 3 | = | 20 / 80 | = | 0.25 |

probability that number of heads in trial is | 4 | = | 12 / 80 | = | 0.15 |

The yearly attendance at a ballpark is shown in the table.

Which answer describes the average rate of change from Year 2 to Year 5?

average rate of change from year 2 to year 5 = \( \frac{\text{333,700 people - 298,300 people}}{\text{5 years - 2 years}}\)

average rate of change from year 2 to year 5 = \( \frac{\text{35,400 people}}{\text{3 years}}\)

average rate of change from year 2 to year 5 = \( \frac{\text{11,800 people}}{\text{1 years}}\)

average rate of change from year 2 to year 5 = 11,800 people per year
