Step-by-step explanation:
1/3 of Vanilla likes both
Vanilla is 2/3 of Chocolate
Chocolate or Vanilla is 3/5
(2/3x-2/9x) + x = 3/5
4/9x + x = 3/5
x(4/9 + 1) = 3/5
x = 3/5*9/13
x = 27/65

Answer:
A. True
Step-by-step explanation:
The empirical rule in statistics states that:
- 68% of the data will be within 1 standard deviation
- 95% of the data will be within 2 standard deviations
- 99.7% of the data will be within 3 standard deviations
So yes, we can state that 5% or less of the data will be more than 2 standard deviations away from the mean. Of course, statistics is not 100% certain, so this rule is not 100% right all the time. Some exceptions might result, but generally speaking, the results should follow the empirical rule.
