How many times more likely is it for a student who took Spanish to have traveled to a Spanish - speaking country than a student who did not take Spanish ?

The complete question is:

The diagram below represents three groups of students:

S (blue and green): The set of students who took a Spanish class.

T (green and orange): The set of students who traveled to a Spanish-speaking country.

D (red and orange): The set of students who did not take a Spanish class. Each block represents one student.

How many times more likely is it for a student who took Spanish to have traveled to a Spanish-speaking country than a student who did not take Spanish?

a. It is 2.3 times as likely.

b. It is 3.3 times as likely.

c. It is 23 times as likely.

d. It is 30 times as likely.

CORRECT OPTION IS B

It is 3.33 times as likely

Step-by-step explanation:

The set of students who took Spanish class = 24

The set of students who travels to Spainish-speaking country = 80

The probability of students traveling to Spainish-speaking country given that they took Spanish Class is 8/24 = 1/3

The probability of students traveling to Spainish-speaking country given they did not take Spanish class is 8/80 = 1/10

Now, the probability that a student travels to a Spainish-speaking country given that the student took Spanish class is 1/3 ÷ 1/10 = 10/3 = 3.33

That is it is 3.33 times as likely

answer: its because of life

step-by-step explanation: i dont know

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
