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.

Why is the jumping off a building is death?
cause you break every bone of your body plus your head
Answer:
Like so many events there is not just one outcome of jumping off a building. Many people die from jumping from tall building but survive jumps from smaller buildings. Human survival of falls from the 17th floor of buildings has been recorded and several parachutists have survived falls from altitudes far taller than any building.
Death in falls usually occurs when the falling person hitting head on when landing or if the body lands on a hard (unyielding) surface. A unyielding surface causes a sudden deceleration. The body acts as fluid and spreads sidewards rupturing many internal organs and causing the brain to splash against the downward side of the skull.
Interestingly a significant amount of work has been done on the defenestration of cats in New York city (Defenestration is the technical term for jumping ot of windows). Cats dropping from 6 floors up or so die. Above the 9th floor they live. This is thought to be due to cats reaching a lower terminal velocity if they have time to relax on the way down.
Can a entire population be measured not just a sample?
Yes it can; given that the population number is reasonable and it can be done in a reasonable amount of time.

How does probability relate to the punnet square?
A Punnet square is a way of representing the possible combinations of genotypes in an offspring of two parents with differing genes. It is used to determine the probability that the offspring has a particular genotype.
What is the probability of producing dwarf plants with white flowers?
It depends upon what the parents were.
If both parents were dwarf and white, then it is 100%
If both parents were heterozygous for both traits, then it is 1/16.
If either parent were homozygous tall and colored, then it is 0.
Make a Punnett Square to get all of the probabilities if you know the genotypes of the parents.

What are the Odds of all 4 players in a foursome getting a hole in one?

How many poker hands with 5 cards contain 3 clubs and two hearts?
13 13
# of poker hands with 3 clubs & 2 heards = ( ) ( )
3 2
= (13!)( 13!) / (10!*3!*11!*2)
= (13!)( 13!) / (10!*11!*12)
= (13!)( 13!) / (10!*12!)
= 13 * 13* 12 * 11
= 22308 #
