Two urns contain white balls and yellow balls. the first urn contains 9 white balls and 9 yellow balls and the second urn contains 8 white balls and 3 yellow balls. a ball is drawn at random from each urn. what is the probability that both balls are white?

Probability that both balls are white is  

Step-by-step explanation:

Since we have given that

Number of urns = 2

In first urn,

Number of white balls = 9

Number of yellow balls = 9

Total number of balls =18

Probability of getting white ball from first urn is given by

In second urn,

Number of white balls = 8

Number of yellow balls = 3

Total number of balls= 11

Probability of getting yellow ball from second urn is given by

Now, Probability that both balls are white is given by

Hence, probability that both balls are white is
