Question

the conditional relative frequency table was generated using data that compared the outside temperature each day to whether it rained that day. given that it was less than 80° on a given day, what is the probability that it also rained that day? 0.3 0.35 0.65 0.7 weather rain no rain total 80°f or greater 0.35 0.65 1.0 less than 80°f 0.3 0.7 1.0 total ~0.33 ~0.67 1.0

Explanation:

Step1: Identify relevant data

We want the probability of rain given temperature < 80°F. From the table, the conditional - relative frequency of rain when temperature is less than 80°F is in the "Less than 80°F" row and "Rain" column.

Step2: Determine the probability

The value in the "Less than 80°F" row and "Rain" column is 0.3.

Answer:

0.3
