Step-by-step explanation:

We have these following informations:

There are 1000 people in total.

540 favored raising the age. Of them 390 were female, and 540-390 = 150 were male.

460 were opposed. Of them, 130 were female and 460-130 = 330 were males.

If a person selected at random from this group is a man, what is the probability that the person favors raising the drinking age?

There are 150+330 = 480 males. Of them, 150 favors raising the drinking age.

So

If a person selected at random from this group is a man, there is a 31.25% probability that the person favors raising the drinking age.
