Solution
Step 1
Write out the expression for the probability of an event occurring
[tex]Pr(\text{ event occurring)}=\frac{Number\text{ of required events}}{\text{Total number of events}}[/tex]For this question,
The number of required events = The number of students that are male and Junior= 2
The total number of events = The total number of male students= 4+6+2+2 = 14
Step 2
Find the required probability after substitution
[tex]Pr(\text{student }is\text{ a junior given its male) =}\frac{2}{14}=\frac{1}{7}[/tex]Hence the probability the student is a junior given its a male = 1/7
In percentage, the probability will be
[tex]\begin{gathered} \frac{1}{\frac{1}{7}}=\frac{100}{x} \\ \text{x =}\frac{1}{7}\times100 \\ \text{x = 14.29\%} \end{gathered}[/tex]
Where x is the required percentage, to the nearest whole percent, the final answer is 14%
