EXPLANATION:
To find out how many blue marbles Ashley would draw in 300 trials, we must do the following:
The results table shows us that for 30 times 6 blue marbles were drawn; then we must make a mathematical relation of proportions or rule of three
The exercise is as follows:
[tex]\begin{gathered} for\text{ 30}\rightarrow6 \\ \text{for }300\rightarrow x\text{ (}how\text{ many blue }marbles\text{ will be drawn)} \\ \frac{300\times6}{30}=\frac{1800}{30}=60 \\ \text{ANSWER: 60 }blue\text{ marbles }could\text{ }be\text{ drawn(option B)} \end{gathered}[/tex]
