A bag contains 5 yellow marbles and 10 blue marbles. If a representative sample contains 2 yellow marbles, then how many blue marbles would you expect it to contain? Explain. Because the ratio of yellow marbles to blue marbles is blank in the population, the expected number of blue marbles is blank times the number of yellow marbles in the representative sample. There should be blank blue marbles.
