Online Probabilities Tutors Probability plays a very pivotal role in mathematics. Probability is defined as the chances for an event to occur. For a given situation or conditions there is always a chances for an event to likely or unlikely occur. The probability of a event is mostly between 0 to 1. The chances or probability for all the possible events to occur for a given condition add up to a 1. Therefore probability of an event is calculated by: P (Event) = Number of outcomes favorable for the event/Total number of outcomes. Example 1: A coin is tossed what is the probability of getting a heads? Solution: On tossing a coin there are total of two possibilities either heads may show up or tails may show up. Therefore total number of possible outcomes = 2. The number of outcomes favorable of getting heads = 1. P (Heads) = Number of outcomes favorable for heads/Total number of outcomes. Therefore probability of getting heads P (H) = 1/2. Example 2: A dice is thrown what is the probability of getting the number 6? Solution: On throwing a dice the total number of possibilities are 6 either of the following numbers may show up i.e. {1, 2, 3, 4, 5, and 6}. Therefore total number of possible outcomes on throwing a dice = 6. The number of outcomes favorable of getting the number 6 = 1. P (6) = Number of outcomes favorable for number 6/Total number of outcomes. = 1/6. Therefore probability of getting number 6 is P (6) = 1/6.
