There are 12 people who are freshmen and who got an A. Look in the "A" row and the "Fr" (freshmen) column.


There are 100 people total.


So,


P(the student got an A AND is a Freshman) = (number who are freshmen AND got an A)/(number total)
P(the student got an A AND is a Freshman) = 12/100
P(the student got an A AND is a Freshman) = <font color="red">0.12</font>
