In a warehouse, there are 40 guitars, 60 bass guitars, and 20 snare drums. an instrument is randomly selected to check the storage conditions. drag and drop the correct value into the box to complete the statement. the probability that the selected instrument is a snare drum is

1: 4/5
2: 1/5
3: 5/6
4: 1/6

 The correct option is (4)

Step-by-step explanation:  Given that in a warehouse,  there are 40 guitars, 60 bass guitars, and 20 snare drums.  An instrument is randomly selected to check the storage conditions.

We are to find the probability that the selected instrument is a snare drum.

Let, S be the sample space for the experiment of selecting an instrument and E be the event that the selected instrument is a snare drum.

Then,

n(S) = 40 + 60 + 20 = 120

and

n(E) = 20.

Therefore, the probability of the event E is given by

Thus, the required probability is

Option (4) is CORRECT.
