Statistics
Statistics deals with collecting, organizing, and interpreting numerical data. An important aspect of statistics is the analysis of population characteristics inferred from sampling.

Why logarithmic function is used to represent information?
I believe that Logarithmic functions are used to represent information because they are calculated and people take the time to actually put effort into finding an answer, and graphing it.
What are the chances of rolling the dice at 1?
For a six sided die , it would be 1/6 as there is an equal chance for every value.
How many numbers start from 1000 up to 9999 which all the digits in all places are even numbers?
4*5*5*5 = 500

A sum that is a factor of 6 has a greater probability.to my dick
The median.
How many people would you need to get together to have two people with a birthday in the same month?
To be certain of it, you would need twelve people (simply because that is the number of different possibilities).
To have a better than even chance of it, you would need at least 5 people.
And the correct answer will of course be - 13
If you have 12, they might all have birthdays in different months.
A better than even chance will have to be more than 6 and therefore that answer would be 7.
How many times will a roulette wheel will stop on 0 if spun 190 times?
There are two different kinds of roulette wheels: those with numbers 1-36, 0 and 00 and ones without the 00. The first one will be expected to stop on zero 5 times, the second 5.14 times.
How many positive numbers have a ones digit of 2?
There are infinitely many such - every tenth number after 2 ends in 2.
What kind sampling based on probability?
Probability sampling, according to which, a member of the population has the same probability of being included in the sample as any other member. Equivalently, each sample of a given size has the same probability of being chosen.
Stratified and cluster sampling are variations on this idea. In stratified sampling, the population can be divided up into strata such that members within each stratum are more like each other than across strata. One example may be school pupils in different year groups. A sampling scheme could assign a number to be sampled from each stratum (perhaps according to how large that group is) and then, within that stratum, to use simple probability sampling.
Cluster sampling is used when the entire population can be split up into clusters. Clusters are selected using probability sampling. Then a census is used within each cluster. For example, if you wanted to sample schools across the country, a simple probability sample would result in schools all over the country and the travelling costs (and time) would be prohibitive. Instead, you divide the country up into regions and take a probability sample of these regions. You end up visiting every school within the few selected regions.

Larger numbers can be made by cascading the powers, but not on here because the notation won't take it.
No.
How do you find a missing cats owners number?
If you found the cat - have it scanned by animal welfare, to see if it has been micro-chipped. The microchip will have a number, which can be matched on a national database to the legal owner.
What is the probability of flipping a coin 4 times and getting heads each time?
The probability on the first flip is 50% .
The probability on the 2nd flip is 50% .
The probability on the 3rd flip is 50% .
The probability on the 4th flip is 50% .
The probability of 4 heads is (50% x 50% x 50% x 50%) = (0.5)4 = 1/16 = 6.25%
What is the point where the line of long meet called?
The lines of longitude meet at the north and south poles.
What is the least product possible when you multiply 1 digit tt greater than 0by a2 digit number?
Since the 1-digit number is explicitly required to be positive but the 2-digit number is not so constrained, the obvious solution is to make the 2-digit number negative.
This gives 9*(-99) = -891
What is the formula for the deviation?
Standard deviation is a way to describe how the data is distributed around the Arithmatic Mean. It is not a simple formula to calculate, as shown in the links.
