There are 4 tens and 13 spades but one of these is the ten of spades.
So there are 4 + 13 - 1 = 16 cards which lead to "success".
Therefore the probability is 16/52 = 4/13
It is 1/4.
The answer depends on how many cards are picked, whether they are picked at random, from what sort of pack, and whether or not cards are replaced before the next one is picked. The probability that a single card, picked at random from a regular 52 card deck is red, is 0.5
3/4
The probability of drawing a spade is 1/4 (13/52). The probability of drawing a face card is 3/13 (12/52). The probability of drawing a spade face card is 3/52 (3/52). 13 + 12 - 3 = 22 The probability of drawing a spade or a face card is 11/26 (22/52).
The probability that a random card picked from a standard pack is a Jack is 1/13.
The probability that it is a spade when drawn is 13/52 or 1/4.
On a random draw of a single card, the probability is 3/4.
It is 1/4.
The answer depends on how many cards are picked, whether they are picked at random, from what sort of pack, and whether or not cards are replaced before the next one is picked. The probability that a single card, picked at random from a regular 52 card deck is red, is 0.5
3/4
The answer depends on how many cards are drawn. If you draw 40 cards, the probability is 0. The probability of not drawing a spade in a random draw of one card from a standard deck is 39/52 = 3/4.
The probability of drawing a spade is 1/4 (13/52). The probability of drawing a face card is 3/13 (12/52). The probability of drawing a spade face card is 3/52 (3/52). 13 + 12 - 3 = 22 The probability of drawing a spade or a face card is 11/26 (22/52).
The probability that a random card picked from a standard pack is a Jack is 1/13.
The probability is 0. One card cannot be a club and a spade!
The answer depends on how many cards are picked. If it is only one random card, then the answer is 1/13.
If you pick enough cards, the probability is 1. For a single card, picked at random, the probability is 1/13.
For a single card, picked at random from a well shuffled normal pack the probability is 3/13.
