A card is drawn from a well shuffled deck of 52 cards. Find P(drawing an ace or a 9).

To find the probability of something you divide the number of ways that the something could occur (in this case the number of cards that meet the criteria of being either an ace or a 9) by the total number of possible outcomes (in this case the number of cards in a deck). Post back with the answer you get and we'll check it for you.
