Explanation:

Step1: Count the number of Xs for each value

For \(0\): \(6\) Xs.
For \(1\): \(7\) Xs.
For \(2\): \(5\) Xs.
For \(3\): \(1\) Xs.
For \(4\): \(10\) Xs.
For \(5\): \(8\) Xs.

Step2: Sum up the counts

\(6 + 7+5 + 1+10+8\)
\(= (6 + 7)+(5 + 1)+(10 + 8)\)
\(= 13+6 + 18\)
\(=19+18\)
\(= 37\)

Answer:

\(37\)
