Find the expected value of each case
<span>1 comes up ---> 1/6 (-10) = -10/6 </span>
<span>3 comes up ---> 1/6 (-30) = -30/6 </span>
<span>5 comes up ---> 1/6 (-50) = -50/6 </span>
<span>2 comes up ---> 1/6 (10) = 10/6 </span>
<span>4 comes up ---> 1/6 (20) = 20/6 </span>
<span>6 comes up ---> 1/6 (30) = 30/6 </span>
<span>sum = 1/6 (-10 -30 -50 +10 +20 +30) = -30/6 = -5 </span>
