A focus group is currently made up of x men and y women. If 3 men and 7 women are added to the group, and if one person is selected at random from the larger focus group, then what is the probability that a man is selected?
Choose the correct choice from the following choices: A) x/(x + 7) B) x/(x + y) C) (y + 3)/(x + y + 7) D) (y + 4)/(x + y + 10) E) (x + 3)/(x + y + 10)
x men   y women   x+3+y+7 is the total   =x+y+10   x+3 is the number of men   so (x + 3)/(x + y + 10)   E. (x + 3)/(x + y + 10)
