Suppose probability of drawing a red marble is p. Then p = 2*(1 - p) that is p = 2 - 2p or p = 2/3 So 2/3 of the 24 marbles are red 24*(2/3) = 16 red marbles.
The probability is 0.3692
probability is a math goodie. like two to four. if you have four marbles in a bag and two are red and two are purple then what is the probability? the answer is fifty to fifty or two two four.
The probability is 0.56

It is 1248/57120 = 13/595 = 0.0218 approx.
To find the probability of picking a red marble, first determine the total number of marbles in the bag, which is 3 (green) + 2 (yellow) + 6 (blue) + 9 (red) = 20 marbles. The number of red marbles is 9. Therefore, the probability of picking a red marble is the number of red marbles divided by the total number of marbles, which is 9/20 or 0.45.
The probability depends on the availability of marbles of those colours to the person making up the bag.
0No blue marbles in the bag.
20% (or 2 in 10 chance)
The probability is 2/15.

The chance of pulling a red marble from a bag without looking depends on the total number of marbles and the number of red marbles in the bag. If there are, for example, 5 red marbles and 15 total marbles, the probability would be 5 out of 15, or 1 in 3. To find the exact probability, divide the number of red marbles by the total number of marbles.
