What is meant by the probability of an event? Discuss how addition and multiplication techniques are used to solve probability problems.

(a) Probability is the chance that a particular outcome will occur when a random experiment (such as tossing a fair coin) is performed. Probability of an event A is the ratio of the number of favorable outcomes to the total number of outcomes.

If we rolled a standard 6-faced fair die once, the probability of getting a 6 is 1/6; that is, if the die is rolled repeatedly n number of times, in the long run, we can expect 6 to occur approximately (n/6) times.

(b) The addition rule of probability is used to determine the probability that event A or event B occurs or both occur.

Mathematically, ...
