Since there are 13 spades and 52 cards, the probability is 13/52 or 1/4=.25
The probability of drawing a spade from a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.
This is the same as the probability of choosing either a red of a blue marble. There are 5+4 out of 15 ways of doing this. The probability is therefore 9/15 = 3/5.
The probability that it is a spade when drawn is 13/52 or 1/4.
The probability of drawing a jack is 4 in 52. The probability of drawing a spade is 13 in 52. The probability of drawing a jack or a spade is 4 + 13 - 1 in 52, with the -1 compensating for one of the jacks also being a spade. 4 + 13 - 1 in 52 is 16 in 52, which is also 4 in 13, or about 0.3077.
1 in four chance.
It is 1/169 or 0.0059, approx.
It is 13/51.
The probability of drawing a red card followed by a spade is (1 in 2) times (1 in 4), or 1 in 8, or 0.125. The probability of drawing a spade followed by a red card is (1 in 4) times (1 in 2), or 1 in 8, or 0.125. Since you have two distinct desired outcomes, add them together, giving a probability of drawing a red card and a spade of 0.25.
Since there are 13 spades and 52 cards, the probability is 13/52 or 1/4=.25
Since there are 2 red tens in a deck of 52 cards, the probability of choosing a red ten is 2 out of 52 = 1 out of 26 = 0,0384615385...
There are 26 red cards and 13 spades in a standard deck of 52 cards. The probability of drawing a red card or a spade in one draw is, therefore, 39 in 52. If you draw twocards, and the first is not red or spade, then the probability on the second draw is 39 in 51, otherwise it is 38 in 51.Combining these two probabilities is easy. Just turn the problem around, and ask what is the probability of drawing two clubs? The answer is (13 in 52) times (12 in 51), which is 156 in 2652, or 1 in 17. Flip that answer over by subtracting it from 1, and you get a probability of drawing a red card or a spade in two draws of 16 in 17, or about 0.9412.
The probability is 0.
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
Since you didn't specify the suit of the jack, there are two possible answers. If the jack was a spade, the probability of drawing another spade is 12/51 or 23.5%. If the jack was NOT a spade, the probability of drawing a spade is 13/52 or 25%.
The probability, or probility, even, is 0 since tere can be no such thing as "choosing red card of the black".
More information is required. Probability by definition is the proportion of a part, called a sample, to the whole, called a population. Thus in this question, we are given the sample only and without the population, it is impossible to calculate the probability. We need to know the size of the population. As a guide, supposing there are 8 red marbles in a jar containing 40 marbles, then the probability of choosing red is 8/40 or 1: 0.2. There is 20 per cent probability of choosing red.
