A card is selected from an ordinary deck of 52 cards. The probability that the card is a queen or a spade is what?

Think about it Haley.

Well, let's do some card math, shall we?

There are a total of 52 cards in a standard deck. Out of these, there are 4 queens and 13 spades. However, one of the queens is actually a spade queen, so we need to subtract that one from the count.

So, we have 4 queens minus 1 spade queen plus 13 spades, which gives us a total of 16 cards that are either a queen or a spade.

Therefore, the probability of selecting a queen or a spade is 16 out of 52, which can be simplified to 4 out of 13.

In funny terms, you have about a 31% chance of getting a card fit for royalty, or alternatively, a roughly 1 in 3 chance of feeling like you're digging for treasure in a pirate's chest! Argh, matey!

To find the probability that the card is a queen or a spade, we need to determine the number of favorable outcomes and the total number of possible outcomes.

There are four queens in a deck of 52 cards, and there are 13 spades in a deck of 52 cards.

To calculate the probability of a queen or a spade, we need to find the total number of favorable outcomes which includes the four queens and the number of spades (13), subtracting the intersection (1 queen of spades).

Total favorable outcomes = Number of queens + Number of spades - Intersection
= 4 + 13 - 1
= 16

The total number of possible outcomes is 52 since there are 52 cards in a deck.

Now, we can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes:

Probability = Favorable outcomes / Total outcomes
= 16 / 52
≈ 0.308

Therefore, the probability of selecting a card that is a queen or a spade is approximately 0.308 or 30.8%.

Prob = P(queen) + P(spade) - P(the queen of spades)

= 4/52 + 13/52 - 1/5
= 16/52 = 4/13

The probability that it's a queen would be 1/13, because there are 4 out of 52 cards in the deck that is a queen. 4/52 simplifies to 1/13.

The probability that it's a spade would be 1/4, because there are 13 spades out of the 52 cards in the deck. 13/52 reduces to 1/4.
