### Examples

*Algebra 1 Example:*Given the relative frequency table below, the ratio of true positives to false positives can be determined as 7.2 to 4.55, which is about 3 to 2, meaning that a randomly selected person who tests positive for diabetes is about 50% more likely to have diabetes than not have it.

Positive | Negative | Total | |

Has diabetes | 7.2% | 1.8% | 9% |

Doesn't have diabetes | 4.55% | 86.45% | 91% |

### Clarifications

*Clarification 1:*Instruction includes problems involving false positive and false negatives.
