Questions:
1. Find the probability that the student was a male, given that his favorite was chocolate milk tea.
The solution assumes that YOU (not a tutor) make an appropriate Table, adequate to the given description.
Having this Table, the solution is very easy:
You then should select two numbers from the Table:
(a) the total of students in the category "chocolate"
(b) the number of males in the category "chocolate".
As soon as you correctly determine these numbers, the sough probability is the ratio
of the number (b) to the number (a).
You even can solve the problem without making a Table (I don't know what your teacher requires from you as a solution).
Simply extract the needed info (a) and (b) from the given text as I described above, and proceed further as instructed.
Keep in mind that : it is not my task or my duty or my intention.
My task is to instruct / (to explain) you what should do.
Also, did your mother or other relatives teach you to thank those who help you ?
"Given his favorite was chocolate milk tea" means we focus solely on the first row labeled "Chocolate"
There are 8 males that like this flavor out of 20 people who liked this flavor.
8/20 = (4*2)/(4*5) = 2/5 is the probability of selecting a male student given that his favorite was chocolate milk tea.
