Question

Consider the following table with information about a sample of students from GCA and if they had trigonometry before taking AMDM. If a person is randomly selected determine the following probability provided the conditions: P(Trig|Male)

2/11

1/6

11/24

1/3

Answer 1

`(1)/(6)`

Explanation:

The conditional probability P(W|X) means "Probability of W happening GIVEN THAT X has happened".

We want to find P(Trig|Male). This would mean, we want people who are male...then we look, how many of them took Trig.

Looking at the table, row and column of Trig & Male is "8".

Hence, Probability would be 8/48 [48 is the total number of people, given in right bottom most part of the table]

8/48 = 1/6

Correct answer is 2nd option, 1/6
