First we calculate how many ways you can choose four books from a set of eight.
We use the formula n! / [r! * (n-r)!]
8! / [4! * 4!]
= 8*7*6*5 / 4*3*2*1 = 70 ways
Then we have to calculate how many permutations can be made from 4 objects which equals 4*3*2*1 = 24
So, the TOTAL number of ways = 70 * 24 = 1,680

Answer:
183.4286 lbs
Step-by-step explanation:
given that the population of weights for men attending a local health club is normally distributed with a mean of 178-lbs and a standard deviation of 25-lbs.
Total weight in the lift should not exceed 6420 lbs
No of persons limited = 35
Hence average weight of the person that should be below

If the average exceeds 183.4286 pounds then the elevator would be considered overloaded.
