Chance of an event occurring, determined as the: proportion of equally likely outcomes comprising the event, or, proportion of outcomes observed in the long run that comprised the event, or, likelihood of occurring, assessed subjectively. Use capital letters to denote events in probability: h=event of getting a heart. Use p( ) to denote probability of event: p(h)= probability of getting a heart. Probability of an event (p) is expressed as a proportion. The probability of drawing a red card from a normal shuffled deck: ways red event can occur = 26, total number of possibilities = 52. P = . 50: there is a 50-50 chance that the card will be a red suit.
