A Jar Contains 5 Red And 7 Blue Marbles

A draw the tree diagram for the experiment.

A jar contains 5 red and 7 blue marbles.

A bag of marbles contains 5 red 3 blue 2 green and 2 yellow marbles. The random variable represents the number of red marbles that you select. Suppose a jar contains 5 red marbles and 12 blue marbles. A marble is drawn at random from the jar.

A jar contains 3 red marbles 7 green marbles and 10 white marbles. You then pick. P yellow 2 11 the probability of picking either of these colors. A store finds that 32 of people who enter the store will make a purchase.

Now there are 24 marbles left. You want the first marble she picks to be red. A ball is drawn at random. A the marble is red b the marble is odd numbered c the marble is red or odd numbered d the marble is blue and even numbered.

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. If a marble is drawn from the jar at random what is the probability that this marble is white. Total 5 3 2 1 11 so there are 11 marbles total. P green 3 11 same idea for yellow.

A bag contains 5 red marbles 6 white marbles and 8 blue marbles. A jar contains 12 red marbles numbered 1 to 12 and 6 blue marbles numbered 1 to 6. Find the probability of the given event. A jar contains 5 blue marbles 6 green marbles and 3 red marbles.

A the marble is red b the marble is red or odd numbered c the marble is blue and even numbered answer by ikleyn 33701 show source. A jar contains 8 red marbles numbered 1 to 8 and 10 blue marbles numbered 1 to 10. B the first marble is. 5 25 of the marbles are red which can be simplified to 1 5.

A jar contains 4 black marbles and 3 red marbles. Two marbles are drawn without replacement. There are two jars a and b. Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.

You want the second marble she picks to be blue. So we need to first find the total number of marbles. Find the probability of the given event. If you reach in the jar and pull out 2 marbles at random at the same time find the probability that both are red 17 total marbles the 1st pick is 5 17 then 2nd is 4 16 the product is 5 68 makes no difference if you take 2 at a time or 2 different choices without replacement.

B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. During a day 50 people enter the store. A a marble is chosen at random. A marble is drawn at random from the jar.

You randomly select 2 marbles from the jar without replacement. P green or yellow 5 11 probability here is the chance of selection out of a total. Jar a contains 7 red and 2 blue marbles while jar b contains 5 red and 4 blue marbles. A bag contains 5 white balls 4 red balls and 3 green balls.

The probability that we pick one of the 3 green marbles out of the 11 is simply that ratio. A glass jar contains 5 red marbles 4 blue marbles 7 green marbles and 9 yellow marbles. If joan picks 2.
