If two caps are picked at random what is the probability that at least one is red. The chance that exactly two draws will be red is 10 times left frac 1 10 right 2 left frac 9 10 right 3 is the addition rule used in deriving this formula. And then there s one blue marble in the bag. So this is all the possible outcomes.

So i could pick that red marble or that red marble. There s two green marbles in the bag. A box contains 15 blue marbles 25 yellow marbles 20 green marbles and 40 red marbles. Five draws are made at random with replacement.

A jar contains 4 black marbles and 3 red marbles. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. Review exercise 4 p. What is p red then blue 20 43 40 43 20 1849 96 1849.

A box contains 2 blue caps 4 red caps 5 green caps and 1 yellow cap. A assume that the first marble is replaced in the box before drawing the second marble. A box contains one red marble and nine green ones. A box contains three marbles.

Find the probability of selecting one green marble from bag a and one black marble from bag b. Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. A draw the tree diagram for the experiment. So i could pick that green marble or that green marble.

You choose a marbles replace it and choose again. If three marbles are selected at random what is probability that all three marbles will be blue marbles b.
