Answer :

Answer

It is 3.3 times as likely.

Step-by-step explanation

From the graph, the fraction of students who traveled to a Spanish speaking country and took Spanish is:

[tex]have\text{ traveled and took Spanish}=\frac{green\text{ blocks}}{blue\text{ and green blocks}}=\frac{8}{8\times3}=\frac{1}{3}[/tex]

From the graph, the fraction of students who traveled to a Spanish speaking country and did not take Spanish is:

[tex]have\text{ traveled and did not take Spanish =}\frac{orange\text{ blocks}}{orange\text{ and red blocks}}=\frac{8}{8\times10}=\frac{1}{10}[/tex]

Then, the ratio between students who took Spanish and have traveled to a Spanish speaking country and students who did not take Spanish and have traveled to a Spanish speaking country is:

[tex]\frac{have\text{ traveled and took Spanish}}{have\text{ traveled and did not take Spanish}}=\frac{\frac{1}{3}}{\frac{1}{10}}=\frac{10}{3}\approx3.3[/tex]
