Probability 2 Bags Of Marbles

What are the chances of getting a blue marble.

Probability 2 bags of marbles. What is the probability of drawing a red marble out of bag 2 given that you drew a red marble out of bag 1. And so this is sometimes the event in question right over here is picking the yellow marble. Since the probability of drawing a red marble from one bag is independent of the colour of the marble drawn from the other bag the probability is math frac34 times frac34. There are 55 marbles 25 of which are not red p getting a color other than red p 25 55 455 probability of this happening 3 times in a row is.

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. 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 chance is 2 in 5. So the next time. Bag 1 has 5 red and 6 blue marbles. If we got a red marble before then the chance of a blue marble next is 2 in 4.

This is called probability without replacement or dependent probability. So we have a bag with 9 red marbles 2 blue marbles and 3 green marbles in it. Bag 2 has 10 green and 5 red marbles. So that s my bag and we re going to assume that it s a transparent bag so it looks like a vase.

You have two bags of marbles. If we got a blue marble before then the chance of a blue marble. The sample space for the second event is then 19 marbles instead of 20 marbles. But after taking one out the chances change.

So let s draw this bag here. The complement of this is the probability that both marbles are red. Marbles in a bag. 2 blue and 3 red marbles are in a bag.

Find the probability of pulling a yellow marble from a bag with 3 yellow 2 red 2 green and 1 blue i m assuming marbles. We can use a tree diagram to help us find the probability.
