Question

In a game played with a standard deck of cards, each face card has a value of 10 points, each ace has a value of 1 point, and each number card has a value equal to its number. two cards are drawn at random. it at least one card is an ace, what is the probability that the sum of the cards is 7 or less?

Answer 1

Answer: The probability that the sum is less 7 or less is 20/51.

First, we start by selecting an ace because the question says one card is an ace. Therefore, our final probability is out of 51.

Our goal is to have 7 or less. That means we can draw a 2, 3, 4, 5, or 6. Since, there are 4 of each type, we have 4 x 5 = 20 different possibilities.
