But after taking one out the chances change.
P purple marble then a red marble with replace.
What is the probability that you draw.
A black marble first and a purple marble second.
So the next time.
To find the probability of pulling out a blue marble we just divide the amount of blue marbles we have by the total marbles in the jar.
And so this is sometimes the event in question right over here is picking the yellow marble.
So what we do is figure out the probability of pulling out a blue marble and then the probability of pulling out another after not replacing the first.
A bag contains 9 red marbles 8 white marbles and 6 blue marbles.
Find the probability of choosing 3 blue.
B find the probabilities for p at least one black marble p same color p bw p exactly one black marble.
A red marble first and a blue marble second.
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.
A draw the tree diagram for the experiment.
2 blue and 3 red marbles are in a bag.
3 yellow marbles and 2 black marbles.
Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.
If we got a red marble before then the chance of a blue marble next is 2 in 4.
If we got a blue marble before then the chance of a blue marble next is 1 in 4.
Find the probability of choosing a red marble then a white marble if the marbles are replaced.
We calculated p drawing a non red 455.
A red or blue marble.
Find the probability of the first marble being green and the second marble being yellow.
A marble is chosen at random from the jar and replaced.
We will call these event 1 and 2.
What is the probability the third marble is the first red marble.
You draw 4 marbles out at random without replacement.
There are 8 total in the bag and 5 of them are purple so the probability that the first one is purple is.
Once you have chosen the first marble there are only 7 left in the bag since we are doing this without replacement so the probability that the second marble is red given that there are 3 red marbles remaining in the bag is.
1 out of 5 b.
This means the first two are not red.
The first red a jar contains 30 red marbles 12 yellow marbles 8 green marbles and 5 blue marbles you draw and replace marbles 3 times.
What is the p purple red answer choices.
B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3.
4 p red 2 p purple 3 p black 1 you draw a marble out of the bag and then replace it.
The probability of picking a yellow marble.
5 green marbles and 4 yellow marbles in a bag.
The chance is 2 in 5.
If joe picks 2.
