(number of possible successes) / (total number of possible outcomes) .
Possible successes = 4 (aces)
Total possible outcomes = 52 (cards)
Probability of drawing an ace from a full deck =
(4 / 52) = (1 / 13) = 7.69% (rounded)
the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
c. (3,2,6) is the answer.
