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?

The correct answer option is b) .

Step-by-step 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) = × =

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

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
