Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

Which is morehalf pint or 6 inches?
A half pint is a unit of volume. 6 inches is a unit of length. The two units are not comparable.
One and a half. But, since that is not possible, 1 or 2 will have to do.
How do you calculate the confidence interval for a population mea?
It's a mystery. need detetive conan.
When roll a 6 sided die about what fraction of the time would you expect a factor of 20?
About 2/3 of the time.
1/13
thas so true
How do you use the F Test to find the sample size for two sets of data?
The data sets determine the degrees of freedom for the F-test, nit the other way around!
There are 999-99 = 900 3 digit numbers.
Of these 9*10 = 90 are palindromic (read the same either way)
So the probability is 90/900 or 0.1
Is there chance to have a duplicate between the 6 billion people on this planet?
Not unless somebody was cloned.
Does the Student t distribution takes different values for a different sample size?
Yes, but it converges to the Gaussian (Normal) dirstribution for large sample sizes.
It is not possible to answer the question without some information about the variability in the mass of the coins.
If you have a rubbish mint and the masses vary a lot then you will need a much greater sample than if the mint operates effectively.
What is the probability of tossing 2 number cubes 500 times?
The answer depends on your persistence. With people who play dice the probability is close to 1; for older people who grew up playing board games, the probability is close to 1. However, for today's younger people it is likely to be quite close to 0.

If a penny hits you at 126 mph will you die?
I cant imagine there is much research to give you a definite answer to your specific question but I would say it is very unlikely, but could be remotely possible.
We think of anything over 100mph as being fast because we tend to relate that sort of speed to driving a car and generally anything over 60 mph starts to be thought of a 'fast'.
In ballistic terms 126mph is pretty slow and the mass of a penny would not cause great trauma unless it hit you in the eye for example. Anywhere else on the body would probably sting a lot and would probably leave a bruise and possibly break the skin.
What is the chance of picking 3 nickels in a row from a pot of 50 nickels and 100 pennies?
196/5513, or about .0356=3.56%
Assumption
I assume that you are asking what is the probability that the first three coins picked out of the pot are nickels. Obviously the answer would be different if, for example, you are asking what is the probability that if you pick all of the coins out of the pot what is the probability that at some point in picking out coins you will pick three nickels in a row.
Explanation
P(three nickels in a row)=P(first coin picked is a nickel)*P(second coin picked is a nickel given that first coin picked is a nickel)*P(third coin picked is a nickel given that first two coins picked are nickels)=(50/150)*(49/149)*(48/148)=196/5513, or about .0356=3.56%
