1 out of 5 b.
P purple marble then a red marble with replace.
If we got a red marble before then the chance of a blue marble next is 2 in 4.
So the next time.
There are 8 total in the bag and 5 of them are purple so the probability that the first one is purple is.
A black marble first and a purple marble second.
So they say the probability i ll just say p for probability.
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.
What is the probability the third marble is the first red marble.
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.
A bag contains 9 red marbles 8 white marbles and 6 blue marbles.
What are the chances of getting a blue marble.
B find the probabilities for p at least one black marble p same color p bw p exactly one black marble.
A marble is chosen at random from the jar and replaced.
We will call these event 1 and 2.
A red marble first and a blue marble second.
But after taking one out the chances change.
The chance is 2 in 5.
The probability of picking a yellow marble.
You draw 4 marbles out at random without replacement.
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.
This means the first two are not red.
We calculated p drawing a non red 455.
And so this is sometimes the event in question right over here is picking the yellow marble.
A red or blue marble.
B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3.
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.
A draw the tree diagram for the experiment.
What is the probability that you draw.
Then a second marble is chosen at random.
What is the p purple red answer choices.
If we got a blue marble before then the chance of a blue marble next is 1 in 4.
Find the probability of choosing 3 blue.
Find the probability of the first marble being green and the second marble being yellow.
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.
Find the probability of choosing a red marble then a white marble if the marbles are replaced.
Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.
5 green marbles and 4 yellow marbles in a bag.
