solution:
You have only two qualitatively different outcomes possible. Count
the number of ways to get each of the two.
There are just two possible outcomes here: the two missing socks
make a pair (the best case) and the two missing stocks do not make a
pair (the worst case). The total number of different outcomes (the ways
to choose the missing socks) is 10 C 2 = 45.
The number of best-case ones is 5; hence its probability is 5 /45 = 1/9
The number of worst-case ones is 45 − 5 = 40; hence its probability is 40/45 = 8/9.
On average, you should expect 4 • 1/ 9 + 3 • 8 /9 = 28/ 9 = 3 1/ 9 matching pairs.

Explanation: Everything behind 0 is considered a negative
If you want to describe the mass of the water in the pool,
then you'll express it in kilograms.
If you want to describe the volume of the water in the pool,
then you'll express it in Liters.
(Those two numbers will be pretty close to equal.)
1 gallon = 3.785 liters.
24 gallons x 3.785 = 90.84 liters
Round the answer as needed.
