A Jar Contains Only Red White And Blue Marbles

If this jar contains 10 yellow marbles what is the total number of marbles in the jar.

A jar contains only red white and blue marbles. And there are still 5 white marbles. Answer by alan3354 66774 show source. You would do the exact same thing with any other color as long as you re just picking one marble. The marble is white or blue.

You roll a fair die if you get a 2 or a 3 you pick a random marble from jar a and put it in jar b. A bag of marbles contains 5 red 3 blue 2 green and 2 yellow marbles. A jar contains 3 white marbles 4 red marbles and 5 blue marbles. So the probability of white is 5 11.

The marble is blue or red. If one marble is drawn at random from the jar find the probability that. You have 12 marbles total. 1 r b w w b r 2 b w r.

You then pick. A certain jar contains only b black marbles w white marbles and r red 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 white 11 blue and 13 red marbles.

A draw the tree diagram for the experiment. A jar contains 20 marbles. The marble is white or red. The probability of finding a red marble would be the number of red numbers in the jar divided by the total number of marbles in the jar.

The probability of selecting a green marble at random from a jar that contains only green white and yellow marbles is the probability of selecting a white marble at random from the same jar is. There are two jars a and b. 8 20 which equals 2 5. 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 black marbles and 3 red marbles. Find the probability of choosing the given marbles without replacement. Now if you take out one red marble then there are 11 now in the jar. Two marbles are drawn without replacement.

Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. Jar a contains 7 red and 2 blue marbles while jar b contains 5 red and 4 blue marbles. 4 red 6 white and 10 blue. So the probability of drawing red is 3 12 or 1 4 reduced.

So the total amount of marbles in the jar would be 20.
