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