Step-by-step explanation:

Given

See attachment for graph

Required

Find P(Junior|Male)

To do this, we first calculate the total students.

[tex]Total = 4 + 6 + 2 + 2 + 3 + 4 + 6 + 3[/tex]

[tex]Total = 30[/tex]

Next, select the value in the cell that intersects Male and Junior

[tex]Male\ and\ Junior = 2[/tex]

Hence, the probability is

[tex]Pr = \frac{Male\ and\ Junior}{Total}[/tex]

[tex]Pr = \frac{2}{30}[/tex]

[tex]Pr = 0.067[/tex]

Express as percentage

[tex]Pr = 0.067*100\%[/tex]

[tex]Pr = 6.7\%[/tex]

Approximate

[tex]Pr = 7\%[/tex]
