Answer:

On average the carnival gain on each play

Step-by-step explanation:

Given that a pond contains 100 fish: 78 purple, 21 blue, and 1 silver.

Fish            Purple     Blue          Silver    total

Prob          0.78      0.21             0.01      1

Revenue           0.4                0.8            13  

game fee 0.65        0.65            0.65  

Net revenue -0.25      0.15            12.35    

   

Net Rev*Prob -0.195      0.0315   0.1235   -0.04
