there are 5 marbles in a bag 1 is orange 2 are blue and 2 are white. you pick a marble at random without putting the marble back you pick another marble at random what is the probability that you pick an orange and a blue
(1/5)*(2/4) (1/5)*(1/2) (1/10)=10%
3/5 or 60%
3 out of the 5 marbles are either orange or blue, so the answer is 3/5
