Pretty much trade. You give vendor money or currency in return they give you the thing you paid for.
The expected value if I have to pick one package given the price I would have to pay is $0.11.
<h3>What is the expected value?</h3>
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
