A bag contains 4 blue, 6 yellow and 4 green balls and two balls are drawn at random. What is the probability that both the balls are blue?
The probability of drawing a blue ball from the bag on the first draw is 4/14, since there are 4 blue balls out of 14 balls in total.
After the first ball has been drawn, there are 13 balls left in the bag, including 3 blue balls out of 13. Therefore, the probability of drawing another blue ball on the second draw is 3/13.
To find the probability of both events happening together (drawing 2 blue balls), we need to multiply the probabilities of each event. So, the probability of drawing 2 blue balls is:
(4/14) * (3/13) = 12/182 = 6/91
Therefore, the probability of drawing 2 blue balls from the bag is 6/91.
