A Bag Contains 5 Red Marbles 6 White Marbles And 5 Blue Marbles You Draw A Marble Find P Not Red

So the first turn you have a frac 5 11 chance of picking a red marble.

A bag contains 5 red marbles 6 white marbles and 5 blue marbles you draw a marble find p not red. Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. A bag contains 7 red marbles 9 white marbles and 9 blue marbles. You draw 4 marbles out at random without replacement. A bag contains 8 red marbles 4 white marbles and 5 blue marbles.

8c5 23c5 0 0017 what is the probability that exactly two of the marbles are red. We will assume that only two marbles are drawn from the bag and hence there are two cases. Two marbles are drawn without replacement. Find p red and blue.

Multiplying these yields frac 3 11. You can do the second with the same process. 6c4 20c4 0 0031 what is the probability that exactly two of the marbles are red. A bag contains 8 red marbles 5 white marbles and 10 blue marbles.

What is the probability that all the marbles are red. A bag contains 6 red marbles 7 white marbles and 7 blue marbles. A jar contains 4 black marbles and 3 red marbles. The first marble is not returned in the bag before drawing the second.

I like to go step by step with these ones. 6c2 14c2 20c4 0 2917 what is the probability that none of the marbles. A draw the tree diagram for the experiment. What is the probability that exactly two of the marbles are red.

You draw 5 marbles out at random without replacement. What is the probability that all the marbles are red. But then you only have 10 marbles left so the probability of picking a white marble is frac 6 10. You draw 5 marbles out at random without replacement.
