<u>Answer:</u>

The correct answer option is b) $\frac{1}{6}$ .

<u>Step-by-step explanation:</u>

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) = $\frac{7}{14}$ × $\frac{3}{9}$ = $\frac{1}{6}$

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