Let P(B) = probability that the student is male
Use the given table to calculate the probability that the <u>student is male</u>:
And the probability that the <u>student is a freshman </u><u>and </u><u>male:</u>

<u>Conditional Probability Formula</u>
The probability of A given B is:
Substitute the found values into the formula:
Therefore, the probability that the student is a freshman given they are male is 29% (nearest percent).
