James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The results are shown below.Bring lunch: 46 males, 254 femalesBuy lunch: 176 males, 264 females

There are 222 males in total (46 + 176) and 740 people surveyed altogether, so P(male) = 222/740 = 0.3. Of the 440 people who buy lunch (176 + 264), 176 are male, so P(male | buys lunch) = 176/440 = 0.4. Therefore, choice D is correct.
