To find the probability of drawing a king or queen from a standard deck of 52 cards, we need to determine the number of king cards and queen cards in the deck.
There are 4 king cards (one king for each suit - hearts, diamonds, clubs, and spades) and 4 queen cards (one queen for each suit). So, in total, there are 8 cards that are either a king or a queen.
Now, to determine the probability of drawing a king or queen, we divide the number of favorable outcomes (8) by the number of possible outcomes (52), which gives:
Probability = number of favorable outcomes / number of possible outcomes
Probability = 8 / 52
Simplifying this fraction, we have:
Probability = 2 / 13
Therefore, the probability of drawing a king or queen from a standard deck is 2/13.
So, the correct answer is B) 2/13.
Either-or probabilities are found by adding the individual probabilities.
4/52 + 4/52 = ?
