23/26
Answer Explanation
Correct answers:
•    23/26
Use the complement rule to find this probability. The complement of this event is the event that the card chosen has a letter among the letters H through J, inclusive?. There are 3 of these letters so the probability of drawing a card with one of these letters is 326. The probability of the complement is 1−3/26=23/26.
