A jar contains only red white and blue marbles. You have 12 marbles total. And there are still 5 white marbles. Now if you take out one red marble then there are 11 now in the jar. 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.

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 jar contains 20 marbles. You would do the exact same thing with any other color as long as you re just picking one marble. Find the probability of choosing the given marbles without replacement.

You then pick. A draw the tree diagram for the experiment. 1 r b w w b r 2 b w r. So the probability of drawing red is 3 12 or 1 4 reduced.

8 20 which equals 2 5. Answer by alan3354 66774 show source. A certain jar contains only b black marbles w white marbles and r red marbles. Jar a contains 7 red and 2 blue marbles while jar b contains 5 red and 4 blue marbles.

P red blue 2 p blue and blue answer by edwin mccravy 18224 show source. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. 4 red 6 white and 10 blue. 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.

The marble is white or blue. The marble is white or red. The marble is blue or red. Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.

So the total amount of marbles in the jar would be 20. So the probability of white is 5 11. A jar contains blue green and white marbles. A jar contains 4 white 11 blue and 13 red marbles.

A jar contains 3 white marbles 4 red marbles and 5 blue marbles. If one marble is drawn at random from the jar find the probability that. There are two jars a and b. If this jar contains 10 yellow marbles what is the total number of marbles in the jar.

A bag of marbles contains 5 red 3 blue 2 green and 2 yellow marbles.
