A Jar Contains 10 Red Marbles 4 White

A jar contains 5 blue marbles 8 red marbles 4 white marbles and 3 purple marbles.

A jar contains 10 red marbles 4 white. 10 x 30 red marbles green marbles i e. Two marbles are drawn without replacement. P white then purple then black independent. Now if you take out one red marble then there are 11 now in the jar.

Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. If a marble is drawn from the jar at random what is the probability that the marble is white. You have 12 marbles total. Now the number of red marbles becomes.

A jar contains 2 pink 6 red and 4 blue marbles. The jar contains 3 red marbles 10 blue marbles 8 green marbles and 4 yellow marbles. 10 x number of green marbles remains 30 hence total number of marbles becomes. Asked 3d a jar contains 3 red marbles 7 green marbles and 10 white marbles.

Show transcribed image text. If a marble is drawn from the jar at random what is the probability that this marble is white. If you pick one marble without looking what is the probability that the marble you pick will be red or blue. Suppose you pick a marble.

A jar contains 20 marbles. So the probability of drawing red is 3 12 or 1 4 reduced. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. Chips are selected randomly one at a time and are not replaced.

And there are still 5 white marbles. The answer is. A jar contains 4 white chips 5 purple chips and 1 black chip. So the probability of white is 5 11.

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. 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. If you randomly select a marble from the jar what is the probability that you will get a white marble.

You randomly choose a marble from a jar. 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. 4 red 6 white and 10 blue. A draw the tree diagram for the experiment.

35 let us consider the number of red marbles added be x. A jar contains 3 red marbles 7 green marbles and 10 white marbles.
