You asked about probability. Probability refers to the likelihood of something happening. It is analyzed through statistics. 

Whenever there is uncertainty about an outcome, probability can be calculated to determine the likelihood of different outcomes. 

A common example is flipping a coin. This has two possible outcomes: heads or tails. To calculate the probability of the coin landing on heads, the equation P(H)=? can be used, and it is commonly known to be a 50% chance or half/half likelihood.
