a black one
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.
50/50 or the same as head or tails with a coin
(3/7)*(2/7)=(6/49) You have a 6 out of 49 probability.

i think it would b 1 out of 12
a black one
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.

3/6 or 1/2 or 50%
The probability, if the cards are not replaced, is 2,535,000/6,497,400 = 0.3902 approx.
It is 5/52 for a single card, drawn randomly.
50/50 or the same as head or tails with a coin
About a 3.8% chance (2 / 52 = 0.038...).
