So the probability of white is 5 11. A draw the tree diagram for the experiment. You randomly choose a marble from a jar. P white then purple then black independent.

A jar contains 20 marbles. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. A jar contains 4 white chips 5 purple chips and 1 black chip. And there are still 5 white marbles.

If a marble is drawn from the jar at random what is the probability that this marble is white. 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. Chips are selected randomly one at a time and are not replaced. Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.

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. A jar contains 4 black marbles and 3 red marbles. So the probability of drawing red is 3 12 or 1 4 reduced. 10 x 30 red marbles green marbles i e.

Suppose you pick a marble. The answer is. 10 x number of green marbles remains 30 hence total number of marbles becomes. A jar contains 10 black marbles and 40 white marbles.

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. Now if you take out one red marble then there are 11 now in the jar. A jar contains 5 blue marbles 8 red marbles 4 white marbles and 3 purple marbles. Two marbles are drawn without replacement.
