Question Help

A bag contains 9 white marbles and 54 red marbles. If a representative sample contains 2 white

marbles, then how many red marbles would you expect it to contain? Explain.

Because the ratio of white marbles to red marbles is in the population, the expected number of

red marbles is times the number of white marbles in the representative sample. There should be

red marbles.
