If A comes then $8. This will happen with probability 1/6 as shown in pie chart
If D penny, will happen with probability 1/3
If B or C then we wins nothing, will happen with probability 1/3 +1/6
Expected winnings is the weighted sum of probability and winnings of each case
= $8*1/6 + $.01*1/3 + (1/3+1/6)*$0
