For a single random choice from a standard deck, the probability is 1/13.For a single random choice from a standard deck, the probability is 1/13.For a single random choice from a standard deck, the probability is 1/13.For a single random choice from a standard deck, the probability is 1/13.
As there are no 12 cards in a standard pack the probability is zero.
On one random draw, the probability is 2/13.
It is 3/13.
The probability of doing so, eventually, is 1. In a single random draw it is 1/52.

"Playing cards" are chosen at random.
4/52
It is 3/13.
The probability of doing so, eventually, is 1. In a single random draw it is 1/52.
Probability of not blue is the probability of white. The probability of white is 11/(11+21) or 11/32.
If the pick is completely random, the deck is a standard deck and there are no jokers or any other cards other than the standard 52, the probability is 1/4
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 that a random card picked from a standard pack is a Jack is 1/13.
You find the event space for the random variable that is the required sum and then calculate the probabilities of each favourable outcome. In the simplest case it is a convolution of the probability distribution functions.
