Answer:
THERE YA GO BUDDY!!
Explanation:
To work out the probability that both randomly chosen students have only visited Mexico, we need to consider the number of students who have visited Mexico and subtract those who have also visited other countries.
From the given information:
- 11 students have visited Canada
- 2 students have visited Canada and Mexico (but not the USA)
- 3 students have visited Mexico and the USA
- 1 student has visited all three countries
- 6 out of the 19 students who have visited the USA have also visited at least one of the other countries.
We can calculate the number of students who have only visited Mexico as follows:
Total students who have visited Mexico = Total students who have visited Mexico and the USA - Students who have visited all three countries - Students who have visited Canada and Mexico (but not the USA)
= 3 - 1 - 2
= 0
Since there are no students who have only visited Mexico, the probability that both randomly chosen students have only visited Mexico is 0.
