Combination question

Generally

nCr = n! / (n-r)!r!

The organizer want to select 5 people from 30 people

Then, the total possible selection is

30C5 = 30! / (30-5)!5!

30C5 = 30•29•28•27•26•25!/25! ×5!

30C5 = 17,100,720 /5•4•3•2

30C5 = 142,506 ways

So, there are 142,506 numbers of ways to selected them.

The group of 5 youngest persons of 30 is UNIQUE such group of 5 persons from 30, under given conditions..

if there are exactly 5 youngest people and if they were all selected, the probability is

5 / 142,506 = 0.000035086

Last year, the numbers of skateboards produced per day at a certain factory were normally distributed with a mean of 20,500 skat

alisha [4.7K]

Answer:

This can be solved by using the empirical rule for a normal distribution.

Step-by-step explanation:

A. The number of skateboards given is one standard deviation above the mean. Approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean. Therefore the required percentage is:

68 + 16 = 84%.

B. The given number of skateboards is two standard deviations above the mean. Approximately 95% of the data points lie within the range plus and minus two standard deviations of the mean. Therefore the required percentage is:

5/2 = 2.5%

C.The given number of skateboards is one standard deviations below the mean. Therefore the required percentage is:

16%.
