try
tr ' ' '\n' < powerball.txt | sort | uniq -c | sort -r
There's a space between the first pair of quotes.
cat powerball.txt
Here's the numbers I tested it with
11 12 13 14 16
12 13 14 15 16
13 14 15 16 17
14 15 16 17 18
15 16 17 18 19
tr ' ' '\n' < powerball.txt
translates all spaces to newlines characters, so each ball is on a line
of its own.

sort
sorts the list of balls so all balls with the same number are adjacent.

uniq -c
replaces each sequence of identical numbers with a count of the number
of times the ball occurs. The first number is the frequency, the second
is the ball number:
1 11
2 12
3 13
4 14
4 15
5 16
3 17
2 18
1 19
sort -r
sorts the list of frequencies into reverse order, so the biggest number
is at the top
5 16
4 15
4 14
3 17
3 13
2 18
