If it is an ordinary pack of playing cards then the probability is 0.5
It is 1/4.
The probability that a random card picked from a standard pack is a Jack is 1/13.
For a single card, picked at random from a well shuffled normal pack the probability is 3/13.
It is 50/52 or 0.9615
2/52 or 1/26
One quarter of the pack are CLUB cards. Three quarters of the pack are NOT CLUB cards. So the chance (probability) of picking a CLUB card is 1 out of 4 = 0.25 The chance (probability) of picking a NOT CLUB card is 3 out of 4 = 0.75 Adding the various probabilities the answer must always be 1.0, which is true here. If the probability of something happening is 1.0, that means the probability is "certainty". It is bound to happen.
The probability is 0.25
there are 4 1's or aces in a pack of 52 cards. Probability of picking an ace=4/52=1/13
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
4 out of 52
The probability of picking a black ace in one random draw from a normal pack of playing cards is 1/26.
There are 12 picture cards in a 52-card deck, so 12/52 which simplifies to 3/13, or 23.1%
