4:1/6 if you add all the instruments you get 120 then you divide it by six and you get 20 snare drums

Answer:  The correct option is (4) \dfrac{1}{6}.

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

P(E)=\dfrac{n(E)}{n(S)}=\dfrac{20}{120}=\dfrac{1}{6}.

Thus, the required probability is \dfrac{1}{6}.

Option (4) is CORRECT.

The second side of a triangular deck is 4 feet longer than the shortest side. The third side that is 4 feet shorter than twice t
Svetlanka [38]

The second side of a triangular deck is 4 feet longer than the shortest side

(s+4) = the 2nd side

and a third side that is 4 feet shorter than twice the length of the shortest side.

(2s-4) = the 3rd side

If the perimeter of the deck is 48 ​feet, what are the lengths of the three​ sides?

s + (s+4) + (2s-4) = 48

Combine like terms

s + s + 2s + 4 - 4 = 48

4s = 48

s = 48/4

s = 12 ft is the shortest side

I'll let you find the 2nd and 3rd sides, ensure they add up to 48

Hope this helps!
