The probability that the student, who was chosen at random, was female and got an "A' on the test is <u>0.1645</u>.
<h3>What is probability?</h3>
Probability is the measurement of the likelihood of an event occurring.
The probability that an event occurs can be equal to or less than 1.
<h3>Data and Calculations:</h3>
Grades A B C Total
Male 18 4 17 39
Female 8 3 20 31
Total 26 7 37 70
Probability of being Female and getting an "A" = 0.1645 (31/70 x 26/70)
The probability of being female = 31/70
The probability of getting an "A" = 26/70
Thus, the probability is <u>0.1645</u>.
