Divide the number of the remaining aces by the number of remaining cards.

Practice makes perfect
Dillon randomly selects cards from a deck of 52 cards. So far he selected 3 of clubs, ace of spades, a 4 of clubs, and a 10 of diamonds. We have 1 ace among the 4 selected cards. Since in a full deck of 52 cards there are 4 aces, there are 4 - 1 = 3 aces within the remaining 52- 4 = 48 cards.
Remaining Aces: & & & 4 - 1 = 3
Remaining Cards: & & & 52- 4 = 48
The ratio of remaining aces to remaining cards gives us the probability that the next card will be an ace.
Remaining Aces/Remaining Cards = 3/48
Finally, let's simplify this ratio. Notice that both the numerator and the denominator are divisible by 3 — let's divide both of them by 3.
.3 /3./.48 /3. = 1/16
Therefore, answer a is correct.
