Marbles in a bag probability.

Number of marbles in bag if equal probability of drawing same and different color balls. For example a marble may be taken from a bag with 20 marbles and then a second marble is taken without replacing the first marble. The probability the first marble you pick is red is of course 19 40. 4 are blue and 1 is red.

4 there are 4 blues total number of outcomes. What are the chances of getting a blue marble. So the next time. If we got a red marble before.

Change the problem such that the number of green marbles is a two digit number. The sample space for the second event is then 19 marbles instead of 20 marbles. Number and color of marbles in the bag replacement rule. What is the probability that a blue marble gets picked.

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. Now there are 38 marbles left and 17 are red. Number of ways it can happen. 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.

Now there are 39 marbles left and 18 are red. The chance is 2 in 5 but after taking one out the chances change. Marbles in a bag 2 blue and 3 red marbles are in a bag. 5 there are 5 marbles in total.

There are 5 marbles in a bag. A bag contains contains 20 blue marbles 20 green marbles and 20 red marbles 1 probability. Probability that at least one out of two marbles will be orange 1 probability that both marbles are blue 1 p first marble is blue p second marble is blue 1 3 5 2 4 7 10 method 2.
