If a number is chosen at random from a set that contains only the whole number factors of 24, what is the
probability that the number is either a multiple of four or a multiple of six?
probability that the number is either a multiple of four or a multiple of six?
정답:
5/8
Explanation/Reference:
The set of whole number factors of 24 is {1, 2, 3, 4, 6, 8, 12, 24}. Of these numbers, four (4, 8, 12, 24) are
multiples of four and three (6, 12, 24) are multiples of six. Be sure not to count 12 and 24 twice-there are
five numbers out of the eight factors of 24 that are a multiple of either four or six. Therefore, the probability
of selecting one of these numbers is5/8.
