In blackjack with one card dealt already? What is the probability it is a Ace, given that it is not a face card?
To calculate the probability of drawing an Ace, given that the card is not a face card, we need to know the number of favorable outcomes and the total number of possible outcomes.
In a standard deck of 52 playing cards, there are 4 Aces and a total of 12 face cards (4 Kings, 4 Queens, and 4 Jacks). So, the number of non-face cards is 52 - 12 = 40.
Therefore, the probability of drawing an Ace, given that the card is not a face card, can be calculated as follows:
Probability = (Number of Aces) / (Number of non-face cards)
= 4 / 40
= 1 / 10
= 0.10
So the probability of drawing an Ace, given that the card is not a face card, is 0.10 or 10%.
It's important to note that the probability assumes a fair deck with randomly shuffled cards.
