Sagot :

The expected value if I have to pick one package given the price I would have to pay is $0.11.

What is the expected value?

The expected value is the cost you would have to pay subtracted from the total value of one package.

Total value of one package  =[ (15 x 0.60) + (5 x 0.3) + (20 x 0.7)]/ (20 + 15 + 5) = $0.61

Expected value = $0.61 - $0.50 = $0.11
