Probability either a or b
WebbNow, by looking at the formula, Probability of selecting an ace from a deck is, P (Ace) = (Number of favourable outcomes) / (Total number of favourable outcomes) P (Ace) = 4/52. = 1/13. So we can say that the probability of getting an ace is 1/13. Example 2: Calculate the probability of getting an odd number if a dice is rolled. WebbIf either event A or event B can occur but never both simultaneously, then they are called mutually exclusive events. If two events are mutually exclusive , then the probability of …

The second equality follows from De … WebbThe probability should just be 3/6, or 50%. In practice, we calculate OR probabilities in two ways. The simplest way is to just count up the ways to win, as done above. The other way is to add the individual probabilities, but in order to get rid of any double-counting, we then subtract off the outcomes that overlap.
