Answer:
24
Step-by-step explanation:
If Tim blows out one candle, there are 3 remaining. Then he blows another making 2 left. And finally he blows again leaving 1 left.
4x3x2x1 = 24.
There are 24 different ways to blow out his candle. We must multiply all the numbers together from greatest to least, and then we get the answer. The answer is 24.

Answer:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Let X the random variable that represent interest on this case, and for this case we know the distribution for X is given by:
And let represent the sample mean, the distribution for the sample mean is given by:
On this case
Solution to the problem
We want this probability:
The best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
The answer i'm pretty sure should be C.
