Probability is the likelihood something will happen as opposed to another factor. If you were to toss a coin, the probability of it landing on heads is 1/2. If you toss it again, the probability of getting tails is 1/2.

Sometimes one result can affect the next one, other times it cannot,

The result affects the next if: You have 3 red marbles and 3 blue. You pull out a blue one and do not replace it. It affects is as it could not be chosen again so the probability of another blue goes down 1, as well as the mail number.

It would not if: You do the same as above, but DO replace the removed marble. This is because it can be chosen again, and the Probability and the overall amount stays the same.
