Find the number of times the face 5 is expected to occur in a sequence of 2000 throws of a fair die?
The probability of 5 is 1/6
So the expected number of times the face 5 shows up in 2000 throws is 2000*1/6 = 333.3... .
If using numbers 1 through 5 how many different 3 digit combinations can be made?
5C3 = 5!/[3!*(5-3)!] = 5!/[3!*2!]
= 5*4*3/(3*2*1) = 10
schools,doctors surgery's, shops, library, police station etcetera...etcetera
hope this helps xx

I am not sure what you mean with "use data"; anyway, a typical MP3 takes up about 4 MB. It may take several minutes to send it by e-mail (and, at the other end, to receive it). If your Internet Service Provider limits the amount of data you can transfer each month (or charges you extra when you pass some limit), transferring big files over e-mail will certainly count towards that limit.
How many 3 digit numbers can be made using 3 4 5 6 7 with repeating the numbers?
The general formula is to square the number of digits it could be (in this case 5) by how many spaces there are. So in this case it would be 53 = 125 possible combinations.
There are 15C3 = 15*14*13/(3*2*1) = 455 combinations, and I am NOT even going to try listing them.
Might that be "unceasingly"? If so, it means without end, unstopping, without ceasing; forever.
If you know the average how do you find the numbers?
It's impossible.

You need a little more information than the average.
Quantiles or measured properties that are capable of changing values are called what?
Quantiles are measures of spread or dispersion. Properties that are capable of changing values are variable properties.
How do you estimate a decimal?
1. You must first go to the place in front of the decimal and round that number
2. Do the same for the next number
3. Lastly do the operation to find your answer
