Answer 2

Probability of Drawing a White Ball from the Urn

To calculate the probability of drawing a white ball from the urn, we can use the following formula:

Probability (P) = (Number of favorable outcomes) / (Total number of outcomes)

In this case, the number of favorable outcomes is the number of white balls, and the total number of outcomes is the total number of balls in the urn.

Calculation

Given that there are 10 white balls and 6 black balls in the urn, the total number of balls is 10 + 6 = 16.

Using the probability formula, we can calculate the probability as follows:

Probability (P) = (Number of white balls) / (Total number of balls) P = 10 / 16 P = 5 / 8

So, the probability of drawing a white ball from the urn is 5/8.

This calculation assumes that each ball has an equal probability of being drawn, and the selection is made randomly.

Conclusion

The probability of drawing a white ball from the urn is 5/8.
