A jar contains 10 red marbles 4 white.

Asked 3d a jar contains 3 red marbles 7 green marbles and 10 white marbles. If you pick one marble without looking what is the probability that the marble you pick will be red or blue. If a marble is drawn from the jar at random what is the probability that the marble is white. Now if you take out one red marble then there are 11 now in the jar.

10 x number of green marbles remains 30 hence total number of marbles becomes. This problem has been solved. P white then purple then black independent. Suppose you pick a marble.

And there are still 5 white marbles. A jar contains 5 blue marbles 8 red marbles 4 white marbles and 3 purple marbles. If a marble is drawn from the jar at random what is the probability that this marble is white. The jar contains 3 red marbles 10 blue marbles 8 green marbles and 4 yellow marbles.

A jar contains 4 white chips 5 purple chips and 1 black chip. Right you have a jar with 5 8 4 3 marbles 20 marbles then the probability of picking a blue marble is 5 blue 20 total 0 25 similarly the probability of picking a purple marble is 3 purple 20 total 0 15. A jar contains 4 black marbles and 3 red marbles. 10 x 30 red marbles green marbles i e.

So the probability of white is 5 11. If you remove marbles one at a time randomly what is the minimum number that must be removed to be certain that you have at least 2 marbles of each colour. You have 12 marbles total. If you are selecting a random sample of n 3 marbles and the first 2 marbles are both white what is the probability that the third marble will be black.

The answer is. Chips are selected randomly one at a time and are not replaced. A jar contains 10 black marbles and 40 white marbles. A jar contains 3 red marbles 7 green marbles and 10 white marbles.

What is the probability of choosing a blue marble. So the probability of drawing red is 3 12 or 1 4 reduced. If you randomly select a marble from the jar what is the probability that you will get a white marble. A draw the tree diagram for the experiment.

Now the number of red marbles becomes. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. Two marbles are drawn without replacement. A jar contains 2 pink 6 red and 4 blue marbles.

A jar contains 20 marbles. 35 let us consider the number of red marbles added be x.
