Question

FreshmenBelow, the two-way table is given for aclass of students.Sophomore Juniors SeniorsTotalMale 462 2.Female 3 46 3TotalIf a student is selected at random, find theprobability the student is a junior. Roundto the nearest whole percent.

Answer 1

To the nearest percentage, the probability that the randomly selected student is a junior is 27%

Here, we want to get the probability that a randomly selected student is a junior

From what we have in the table, the total number of students will be;

4 + 3 + 6 + 4 + 2 + 6 + 2 + 3 = 30

The number of juniors we have is ;

2 + 6 = 8

So the probability is simply the number of juniors divided by the total number of students

We have this as;

$\frac{8}{30}\times\text{ 100 \% = 27\%}$
