Question

two urns contain white balls and yellow balls the first urn contains 7 white balls and 7 yellow balls and the second urn contains 3 white balls and 6 yellow balls. a ball is drawn at random from each urn. what is the probability that both balls are white?

Answer 1

The correct answer option is b)
`(1)/(6)`.

Explanation:

We are given that the first urn contains 7 white balls and 7 yellow balls and the second urn contains 3 white balls and 6 yellow balls. We are to find the probability that both balls drawn are white.

This means that the first must be white and the second ball must also be white.

P (w, w) =
`(7)/(14)` ×
`(3)/(9)` =
`(1)/(6)`

Therefore, the probability that both the balls drawn are white is 1/6.
