Answer 1

The Solution:

Given the table below:

We are asked to find the probability that the student preferred morning classes given he or she is a freshman.

By formula,

`\text{Probability =}\frac{\text{ number of required outcomes}}{\text{ number of total outcomes}}`

In this case,

`P(\text{ Preferred morning/he or she freshman)=}(19)/(44)=0.4318\approx0.432`

Therefore, the correct answer is [option 4]
