Solve this if you can :)<br> I will give brainliest
mafiozo [28]

Answer: This question cannot be answered.

Explanation:

If you add three odd numbers, the sum must also be an odd number. To get an even number, you have to add an even number of odd numbers, e.g. 2 or 4. Adding 3 odd numbers to get 30 is therefore not possible. So the question cannot be answered.

A bad contains 8 black,3red and 9 white balls. If 3 balls are drawn at random, find the probability that none is red
LenKa [72]

Argument

You have a total of 8 + 9 + 3 balls = 20

The first ball is 17/20         Probability that no ball drawn is red the first time

The Second ball is 16/19   Probability that no ball drawn is red the 2nd time

The third ball is 15/18        Probability that no ball drawn is red the 3rd time

Answer

Total Probability = 17/20 * 16/19 * 15/18 = 34/57

My calculator figures out fractions. You can do this just as easily with decimals.

0.85 * 0.8421 * 0.8333333 = 0.5964

34/57 = 0.5965  which is close enough.

If you have choices, choose the one that coincides with my answer. Otherwise use the decimal value.
