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.
Answer: attached below
Step-by-step explanation:
L = 10
B = 20
so to find the diagonal you have to use Pythagorean theorem that is a^2 + b^2 = c^2
10^2 + 20^2 = X^2
X = root of 10^2 + 20^2
X = root of 100 + 400
X = root of 500
X = appox 22.36
