There Are Seven Black Marbles And Nine White Marbles

And sometimes this is referred to as the sample space the set of all the possible outcomes.

There are seven black marbles and nine white marbles.

A sample of 12 marbles is to be picked from the box. Three marbles are selected at random and without replacement. Call it the second marble. A bag contains 8 red marbles 5 blue marbles 8 yellow marbles and 6 green marbles.

Take out a marble. Write the probability as a fraction in simplest form a decimal and a percent. What is the approximate probability of drawing two black marbles and then a white marble without replacement. So i could pick that green marble or that green marble.

An urn contains 4 red 6 white and 5 blue marbles. Give your answer as a decimal number with 3 decimal places. B how many samples contain exactly 4 red marbles and exactly 3 black marbles. Trivially then the answer is frac 1 3 since there is one white.
