The probabilities dependent on how many times you filp a coin, using the number of choices or outcomes for 2 independent events and multiply them together. For example, if you are flipping once and want to get a head, the independent event is 1, probability of getting a head from a coin is 1/2, therefore, the probability of getting a head by flipping a coin once is : 1*1/2=1/2
Sometimes when we want to make decisions but there are pros and cons either way, or we don't know what decisions will be a better choices and we still need to make up our minds, doing a coin flip can be an good way for us to make decisions.
If you flip a coin and find yourself want the outcome to be head or tail more, which can also means you have a preference in your mind but you did not realize it. In this case, the actual result of the coin flip should not be matter as you are hidding your preference and want the result of coin flip to help you to speak out. Otherwise, if you are happy with either result, you can let the coin flip to get a random decision you can act on.
There are two possible outcomes of a random coin flip: heads or tails. As the random coin flip generator shown, you can get either result by a chance of 50/50. However, imagining if you flip a coin 5 times and you want the outcomes to be heads in 5 throws. The previous coin flip doesn't influence the next one, so each coin flip has equal chance of coming up either heads ot tails, which means each coin flip is an independent event, and the results are also independent, won't affect by the next throw.
As we all known, each result of a coin flip has a 50/50 chance of landing heads or tails, which means even if you are flipping 100 times, the results won't be exactly 50 heads and 50 tails. But if you are flipping 10 times the chances that you get heads or tails that its close to 50/50 is less than if you flip a coin 100 times. The more you flip, the closer you will get to a 50/50 split. If you are flip a coin 100,000 times, you should be even more closer to get a 50/50 result.
In the 7th century BC, metal coins were first manufactured. The very first coin flipping happened in ancient Rome, at that time,
Romans called coin flip "navia aut caput", which means " ship or head". In Rome, coins had a ship on one side and head of the emperor
on the other side. Julius Caesar endorsed the coin flip in 49 BC. During this time, coin flips were used to make some serious
decisions, such as things related to criminality, property, marriage.etc. The result of these coiin flips were considered to be
Later, a British called coin flip as "cross and pile", since many coins depicted a "cross" on one side and "pile" means "reverse of a coin" in Middle English term. In Peru, coin flip had another name called "face or seal". In ancient China, the game was called "ship or head".
Many historians believe that the coin flip was originated in Ancient Greece. Today, coin flipping can be still found all over the world. Many sports, such as football, tennis, and fencing, we still using coin flip to determine which team goes first in a match, or to determine a winner in the event of a draw.

First flight pilot
On December 14, 1903, Wilbur and Orville (the Wright brothers) were gearing up for the world's first heavier-than-air-flight. In order to decide who can be the pilot, Wilbur decided to do a coin flip. The coin landed in Wilbur's favor, which made him the first chance to fly. However, his first attempt was ended only flying 3.5 seconds with a crash. Three days later, it was Orville's turn and he made the first successful flight.
A coin has 2 possible outcomes since it has heads or tails, which means the probability of landing heads is 1/2. Therefore, the probability of landing on heads is 50%.
We believe the frequency of getting heads and tails should be equal, the more you toss, the closer you will get 50/50 chances of getting heads and tails. However, we are expecting to get between 4900 and 5100 heads when you flip a coin 10000 times.
If an event is certain to happen, the probability is 100%. If an event is equally likely to happens, the probability is 50%. If the probability is less than this, we consider it as unlikely to happen.
It looks like heads and tails are both having 50/50 chances, however, when you flip a coin, the outcomes may affect by gravity.etc, in other words, real life is rarely fair.
It helps you to make decisions, at some points, it is good.
Without fraction, it can, but in real life, no.
