A card is randomly drawn from a deck of 17 identical
cards numbered from 1 to 17. In
the experiment of recording the number written on the card, determine the event that
the recorded number is a multiple of the two numbers 3 and 5.
The cards that are multiples of 3 are 3, 6, 9, 12, and 15, while
the cards that are multiples of 5 are 5, 10, and 15. This means
that the only card that is a multiple of both 3 and 5 is 15. Thus,
the set representing the event for which all cards that are
multiples of both 3 and 5 is .
