Answer 1

29

Explanation:

Use definition of conditional probability:

`P(A|B)=(P(A\cap B))/(P(B)),`

where

A = the student is a freshman,

B = the student is a male

From the table,

`P(B)=(4+6+2+2)/(4+6+2+2+3+4+6+3)=(14)/(30)=(7)/(15)\\ \\P(A\cap B)=(4)/(4+6+2+2+3+4+6+3)=(4)/(30)=(2)/(15)`

So,

`P(A|B)=((2)/(15))/((7)/(15))=(2)/(7)\approx 0.29=29\%`
