Final answer:
The probability of drawing another ace is approximately 6%.
Step-by-step explanation:
In this problem, the friend has already chosen a jack and an ace without replacement. Now we need to determine the probability that the third card drawn will be another ace.
Since the friend already picked a jack and an ace, there are now 50 cards left in the deck. Out of these 50 cards, there are 3 remaining aces. Therefore, the probability of drawing another ace is 3/50. When rounded to the nearest percent, the probability is approximately 6%.
