We take 2 marbles from 20 marbles and the total ways is 20x19:2=190
But we need only 2 red marbles and the ways is 14x13:2=91
And finally we do the division 91:190=91/190 is the probability we need
Answer:
ok
Step-by-step explanation:
Answer: Not a function
<u>Step-by-step explanation:</u>
The graph fails the vertical line test. In other words, when you draw a vertical line anywhere through the curve, the line passes through two points.
Bonus: If you do not have a graph, it is not a function if there is one x-value that has two different y-values.
For example, If (1, 2) and (1, -2) lie on the curve, then it is NOT a function because the x-value (1) has two different y-values (2 & -2).
Considering that the mean of the normal distribution is the same as the median, the median is of 88%.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
For the normal distribution, the median is the same of the mean, that is, the median is of 88%.
