A little old lady lives in a house with only her children and the children each have pets. She has twice as many sons as daughters. Each son has a dog, and each daughter has a cat. If the total number of pets and children living with her are Y, then how many dogs live in the house, in terms of Y  Select:
A) Y/8	B) Y/2	C) 2*Y	D) 3*Y	E) Y/3

Solution: Since Y is the total of all children and pets, Y = Boys + Girls + Dogs + Cats   Since each boy has a dog then, Boys = Dogs. Since each Girl has a Cat then, Girls = Cats   Thus Y = 2*Boys + 2*Girls   Since there are twice as many boys as girls, Girls = Boys/2.   Thus Y = 2*Boys + 2*(Boys/2) Which simplifies to Y = 2*Boys + 1*Boy, or Y = 3*Boys   Since Boys = Dogs ... Y=3*Dogs   Which converts to Dogs = Y/3   Answer: Y/3

A box contains 6 white, 5 red and 8 white marbles. 5 marbles are drawn from the box at random. What is the probability that both the marbles are of the same color?  Choose the correct choice from the following.
A) 19/11628
B) 36/11628
C) 613/11628
D) 6113/11628
E) 63/11628

Solution: Explanation:   Total marbles in a box = 6 black + 5 red + 8 green marbles = 19 marbles   5 marbles are drawn from 19 marbles at random. Therefore,   n(S) = 19C5 = 11628 ways   Let A be the event that 2 marbles drawn at random are of the same color. Number of cases favorable to the event A is   n(A) = 6C5+ 5C5 + 8C5 = 6 +1+ 56= 
6 +1+ 56 = 63
63   Therefore, by definition of probability of event A,   P(A)= n(A)/n(S) = 63/11628   ANSW63/11628R:63/11628
