The rule of inference used to in concluding that Casey has a fever is called the: law of detachment.
The law of detachment states that, if two statements are true, then a third statement would logically be true. For example:
Statement 1: If a, then b,
Statement 2: a, given that statements 1 and 2 are true, then,
Statement 3, b, is true.
We are given that the two statements below are true:
Statement 1: If you have a temperature above 100.4°F (a), then you have a fever (b).
Statement 2: Casey has a temperature of 101.2°F (a), given that the two statements are true, then,
Statement 3, Casey has a fever, is true.
Therefore, the rule of inference used to in concluding that Casey has a fever is called the: law of detachment.
