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.
It is 1/4.
On a random draw of a single card, the probability is 3/4.
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 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 is 0. One card cannot be a club and a spade!
The probability that a random card picked from a standard pack is a Jack is 1/13.
The answer depends on how many cards are picked. If it is only one random card, then the answer is 1/13.
The probability of drawing a red card and a spade in two cards is the probability of drawing a red card multiplied by the probability of drawing a spade, multiplied by 2 (as it doesn't matter which way around they are drawn). The probability of drawing a spade is 1/13 as there are 4 spades and 52 cards. The probability of drawing a red card after this is 26/51 if the spade was black, and 25/51 if the spade was red. This averages at 51/102 Multiply these probabilities together and then multiply by two and we get 51/663 which can be simplified to 1/13
For a single card, picked at random from a well shuffled normal pack the probability is 3/13.
