There are 5 marbles in a bag - 2 are orange and 3 are blue. If two marbles are pulled from the bag, what is the probability that at least one will be orange? Answers.
A) 7/10	B) 3/5	C) 2/5	D) 3/10	E) 1/10
Probability of the first ball being orange = 2/5   The first all is not replaced, hence the total number of balls for the second pick = 1/4   Therefore the total probability is 2/5 x 1/4 = 1/10   Hence 1/10
