Probabilities of Compound Events Worksheets

How to Determine the Probabilities of Compound Events - A compound event is where there is a possibility of more than one possible outcome. Determining the probability of a compound event involves finding the sum of all the probabilities of the event and removing the ones that overlap. Probability is defined as the likelihood of an event to occur. It is normally written in the form of a fraction where the number of favorable outcomes is on the numerator, and the total number of outcomes is in the denominator. Probability is used for determining many things from the likelihood that someone will win a lottery or a baby will be born with a medical problem. Example of compound events are: Chances of rolling a six in a dice: 1/6 Probability of picking a heart from a deck of cards: There is a total of 52 cards out of which 13 will be heart so that probability would be 13/52. Simplifying it further, the probability will be 1/4. These worksheets and lessons will help students predict the possible outcomes of events that have multiple end results.
