Find the probability of finding a red marble out of a bag consisting of 8 green, 5 red and 4 white marbles?
Let E be the event of picking a red marble from the bag
P(E) = (Number of outcomes favourable to E)(Number of all possible outcomes) = 517
A bag contains 5 red marbles, 8 white marbles, 4 green marbles. What is the probability that if one marble is taken out of the bag at random, it will be
(i) red (ii) white (iii) not green
