#16. An urn contains 8 red chips, 10 green chips, and 2 white chips. A chip is drawn and replaced, and then a second chip is drawn. What is the probability of (a) A white chip on the first draw? (b) A white chip on the first draw and a red on the second? (c) Two green chips being drawn? (d) A red chip on the second, given that a white chip was drawn on the first?

00:01 Hello student.
00:02 It is given that two chips drawn at random one at a time without replacement from pack containing two blue chips and two red chips of same color.
00:19 Now here we have to find out the probability of trying a two chip of same color that is either both blue.
00:29 So here that is either both blue or both red.
00:37 So here probability of drawing a first blue.
00:44 So here probability of drawing a first blue which is equals to 2 by 4 which is equals to 1 by 2.
00:54 Now after drawing one blue there is one blue and two red chip left.
00:59 So here probability of drawing a second blue which is equals to 1 by 3.
01:08 Now here probability of both the chips blue.
01:15 So here probability of both blue is equals to 1 by 2 into 1 by 3 which is equal to 1 by 6.
01:27 Now here we have to find out probability of both red chip...
