Answer 1

2 / 9

Explanation:

P(Freshman| Girl) = P(Freshman n Girl) / P(Girl)

P(Freshman n Girl) = n(Freshman n Girl) / n(total)

P(Freshman n Girl) = 4 / 30 = 0.1333

P(girl) = n(girl) / n(total)

P(Girl) = 18/30

Hence,

P(Freshman n Girl) = 4/30 ÷ 18/30

P(Freshman n Girl) = 4/30 * 30/ 18

P(Freshman n Girl) = 4 /18 = 2 / 9
