Answer 8

\[\text{if } x =\text{ the value of the roll,}\]\[\text{ }\langle x\rangle=\text {the expectation value of x,}\]\[N=\text{ is the total number of possibilities} \]\[\text{and the summation is taken over all posible x } \]
\[\langle x\rangle=\sum \frac xN\]
\[\langle x\rangle=\sum \frac x6=\frac {1+2+3+4+5+6}6=\frac{21}6=3.5\]
