If we got a red marble before.

Marbles in a bag probability.

Probability examples a jar contains 30 red marbles 12 yellow marbles 8 green marbles and 5 blue marbles what is the probability that you draw and replace marbles 3 times and you get no red marbles. Marbles in a bag 2 blue and 3 red marbles are in a bag. 4 are blue and 1 is red. What is the probability that a blue marble gets picked.

Using the digits 1 to 9 at most one time each fill in the boxes to make the probability of drawing a red marble from either bag the same. Number of marbles in bag if equal probability of drawing same and different color balls. This is called probability without replacement or dependent probability.

The probability that the second marble is red is 18 39. Number and color of marbles in the bag replacement rule. So the next time. 5 there are 5 marbles in total.

Now there are 39 marbles left and 18 are red. Change the problem such that the number of green marbles is a two digit number. Number of ways it can happen.
