A meeting is attended by 750 professionals. 450 of the attendees are females. Half the femaleattendees are less than thirty years old, and one-fourth of the male attendees are less than thirty yearsold. If one of the attendees of the meeting is selected at random to receive a prize, what is theprobability that the person selected is less than thirty years old?
(A)1/8
(B)1/2
(C)3/8
(D)2/5
(E)3/4

• d)2/5 is probability that the person selected is less than thirty years old.
  
  Let total professionals, X = 750
  And Professional who has less than thirty years = Y
  
  Y = 1/2(450) + 1/4(300)
  Y = 225 + 75
  Y = 300
  
  Probability = Y/X = 300/750 => 30/75 => 2/5
