P Purple Marble Then A Red Marble With Replace

This means the first two are not red.

P purple marble then a red marble with replace.

What is the probability the third marble is the first red marble. The probability of picking a yellow marble. B find the probabilities for p at least one black marble p same color p bw p exactly one black marble. But after taking one out the chances change.

We will call these event 1 and 2. A marble is chosen at random from the jar and replaced. A bag contains 9 red marbles 8 white marbles and 6 blue marbles. 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.

So the next time. A red or blue marble. If joe picks 2. A black marble first and a purple marble second.

Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. 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. 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. Find the probability of choosing 3 blue. 3 yellow marbles and 2 black marbles. 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. The chance is 2 in 5. 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. We calculated p drawing a non red 455.

You draw 4 marbles out at random without replacement. What is the probability that you draw. Find the probability of the first marble being green and the second marble being yellow. If we got a blue marble before then the chance of a blue marble next is 1 in 4.

What are the chances of getting a blue marble. A draw the tree diagram for the experiment. 1 out of 5 b. Then a second marble is chosen at random.

4 p red 2 p purple 3 p black 1 you draw a marble out of the bag and then replace it. There are 8 total in the bag and 5 of them are purple so the probability that the first one is purple is. Find the probability of choosing a red marble then a white marble if the marbles are replaced. 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 red marble first and a blue marble second.
