What is the probability that at least one of the cards is a spade?
Hence for drawing a card from a deck, each outcome has probability 1/52. The probability of an event is the sum of the probabilities of the outcomes in the event, hence the probability of drawing a spade is 13/52 = 1/4, and the probability of drawing a king is 4/52 = 1/13.
What is the probability that at least one of the three cards is a face card?
There are 52 cards in a pack. Therefore the probability of getting no face card is 38/85. Therefore the probability of getting at least one face card is 47/85.
What is the probability of picking a spade from a deck of 52 cards?
13/52
Hence for drawing a card from a deck, each outcome has probability 1/52. The probability of an event is the sum of the probabilities of the outcomes in the event, hence the probability of drawing a spade is 13/52 = 1/4, and the probability of drawing a king is 4/52 = 1/13.
What is the probability of getting a 4?

| 4 | 6/36 (16.667\%) |
| 5 | 10/36 (27.778\%) |
What is the probability of drawing a king or queen from a pack of 52 cards?
2/13
Complete step-by-step answer: Hence the probability of getting a king or a queen out of 52 cards is 2/13.

What’s the probability of drawing a spade?
13 in 52
For example, you can add up the number of spades in a complete deck (13) and divide this by the total number of cards in the deck (52) to get the probability of randomly drawing a spade: 13 in 52, or 25 percent.
What is the probability of drawing all clubs?
The probability of drawing a club is 13/52. The probability of drawing a face card is 12/52. However, three of the clubs are also face cards, so there are only 22 of the 52 cards that are either clubs or face cards. If we simply add 13/52 and 12/52, we count three cards twice.
How do you find the probability of drawing a spade?
If we let A = “Drawing a face card” and B = “Drawing a spade”, we can compute this by finding two values: P (A ∩B), or the probability of drawing a face card which happens to also be a spade, and P (B), or the probability of drawing a spade.
What is the probability of E2 from a deck of cards?
Drawing a King of Spades There are 13 cards in each suit, of which 1 is King. Hence, the probability of event E 2 occuring is P (E 2) = 1/52
What is the probability of drawing a black card from a deck?
∴ ∴ Probability of drawing a black card from a pack of cards is 1/2. Jessica has drawn a card from a well-shuffled deck. Help her find the probability of the card either being red or a King. Jessica knows here that event E is the card drawn being either red or a King. There are 26 red cards, and 4 cards which are Kings.
How many spades are in a deck of 52 cards?
Since there are three face cards (Jack, Queen, and King) in the spades suit, and 52 total possible cards, the P (A ∩B) = 3 52. In a similar fashion, we know there are 13 spades in a deck of 52 cards, so P (B) = 13 52.
