The conditional relative frequency table was generated using data that compared the outside temperature each day to whether it rained that day.

A 4-column table with 3 rows titled weather. The first column has no label with entries 80 degrees F, less than 80 degrees F, total. The second column is labeled rain with entries 0.35, 0.3, nearly equal to 0.33. The third column is labeled no rain with entries 0.65, 0.7, nearly equal to 0.67. The fourth column is labeled total with entries 1.0, 1.0, 1.0.

Given that it was less than 80º on a given day, what is the probability that it also rained that day?

0.3
0.35
0.65
0.7

Respuesta :

Using it's concept, the probability that it rained that day is given by: 0.7.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For this problem, we have that for days in which the temperature was below 80º, the relative frequency of rain is of 0.7, from the column with rows labeled rain, hence the probability that it rained that day is also given by: 0.7.

This is because the concept of relative frequency, just like a probability, is number of desired outcomes divided by the number of total outcomes.
