It is 5/52 for a single card, drawn randomly.

The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.
The probability is 0.
The probability, or probility, even, is 0 since tere can be no such thing as "choosing red card of the black".
1/26

There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.
The probability depends on:whether the cards are drawn randomly,how many cards are drawn, andwhether the cards are replaced before drawing the next card.If only 2 cards are drawn randomly, and without replacement, the probability is 0.00075 approximately.
It is 5/52 for a single card, drawn randomly.
A laundry bag contains 160 black socks and 300 red socks. 1940 black socks must be added so that the probability of choosing a black sock is 7 of 8.
