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.(1 point)

The total number of halls in the museum is 5 + 3 + 4 = 12.

The probability of the closed hall being on the second floor is 3/12 = 1/4.

Therefore, the likelihood of the closed hall being on the second floor is 1/4.
