Question

The diagram below represents three groups of students:

Answer 1

The data is shown in the Venn diagram below

The probability of students traveling to Spain GIVEN that they took Spanish Class is 8 out of 24

The probability of students traveling to Spain GIVEN they did not take Spanish class is 8 out of 80

Hence the probability that a student travels to Spain given that the student took Spanis class is $\frac{1}{3}$÷$\frac{1}{10}$=$\frac{10}{3}$ or 3.33 times likely
