A bag consists of 50 marbles, of which 5 are blue, 9 are red, and the remainder are white. If Lisa is to select a marble from the bag at random, what is the probability that the marble will be red or white?
Select the correct option:
A) 3/4	B) 2/4	C) 1/4	D) 1/8	E) 9/10
bag consists of 50 marbles, of which 5 are blue, 9 are red   remainder are white. So, white = 50 - 5 - 9=

<output>36</output>
36.   probability that the marble will be red or white= probability that the marble will be red + probability that the marble will be white   probability that the marble will be red or white = 9/50+36/50 = 45/50 = 9/10   Hence, answer will be 9/10.
