A science museum has announced that, on a particular day, one of their halls is closed for construction. The museum has 5 halls on the first floor, 3 on the second floor, and 4 on the third floor. How likely is it that the closed hall is on the second floor? Give the answer as a fraction in the simplest form

Answer 1

There are a total of 12 halls in the museum. Since one hall is closed, there are 11 halls available.

There are 3 halls on the second floor, so the probability that the closed hall is on the second floor is 3/11.

Therefore, the likelihood of the closed hall being on the second floor is 3/11.
