The event is that the coin lands with the Heads on top.
It means that two events cover the spectrum of possible events. For instance, with respect to flipping a coin, the event of getting heads and the event of getting tails are mutually exhaustive. There is not another outcome of events possible when flipping a coin.
The probability of flipping a coin 3 times and getting 3 heads is 1/2
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.

As a coin has two sides, the odds are always 50-50.
The sample space when flipping a coin is [heads, tails].

The probability of this is 50%. 2/4
An event is an outcome or set of outcomes of an experiment. For example, if you want a coin to land on heads when you are flipping it, and it DOES land on heads, THAT is the event. If it lands on tails, that outcome is the complement
