Probability concerns numerical descriptions of how likely an event is to occur or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where 0 indicates impossibility of the event and 1 indicates certainty. In this chapter we learn about trials, outcomes, sample space and events, the probability of an event, complementary events, combined events, mutually exclusive events, conditional probability, probabilities of independent events, venn and tree diagrams and lastly table of outcomes.
