What is the probability that the card drawn is an ace or a black card?

However, The probability of getting a black card or an ace [which we may denote as P(black or ace)] is not P(black) + P(ace) since the former is 28/52 (there are 26 black cards and 2 red aces) while the latter is 26/52 + 4/52.

What is the probability of drawing either an ace or a spade?

There are four aces in a standard deck of cards. But one of those aces is also a spade so we don’t count that twice. Hence, there are 12 + 3 or 15 cards that are either an ace or a spade. Since there are 52 cards in a standard deck, the probability would be 15/52.

How many cards are drawn at random from a deck?

Two cards are drawn at random (without replacement) from a regular deck of 52 cards. What is the probability that the first card is a red and the second card is heart? Let $A$ be the event that a red Stack Exchange Network

What is the probability of drawing the second ace of Hearts?

The deck has 52 cards and contains 4 aces. When you draw a card, the probability of drawing an ace is [math]4/52 = 1/13[/math] When the second card is drawn, there are only 51 cards left and since an ace has been drawn already, only 3 of them remain in the deck. Hence probability of drawing the second ace is [math]3/51[/math].

How many aces are in a deck of 52 cards?

There are 4 aces in a deck of 52 cards. When you draw first card the probability of it being an Ace is 4/52. Since you have already drawn a card which is an Ace then there will be remaining 3 aces in 51 cards. So probability of second card being an Ace is 3/51.

What is the probability of drawing a diamond in blackjack?

Since there are 13 diamond cards, the probability of drawing a diamond card is 1 54 ∗ 13; there are 3 cards that are both face and diamond, so the probability of drawing such a card is 3/54. If you use the conditional probability formula for event B (drawing a card that is diamond and face) given event A (drawing a card that is a diamond)]
