If we got a blue marble before then the chance of a blue marble.
Marbles in a bag probabilitty at least one.
B find the probabilities for p at least one black marble p same color p bw p exactly one black marble.
So the next time.
Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.
What are the chances of getting a blue 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.
In a bag of 512 marbles i have 1 red 1 green 3 purple and 507 white.
I know that individually the expected value to pull a red is 512.
Marbles in a bag.
But after taking one out the chances change.
If we got a red marble before then the chance of a blue marble next is 2 in 4.
So they say the probability i ll just say p for probability.
B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3.
The probability of picking a yellow marble.
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.
The chance is 2 in 5.
And so this is sometimes the event in question right over here is picking the yellow marble.
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.
2 blue and 3 red marbles are in a bag.
I am considering a problem where the goal is to calculate the expected number of marbles pulls required to get at least 1 of each rare marble color with replacement.
Given a bag with 2 green marbles 5 red marbles and 3 yellow marbles.
