Expected Value Exercise 5



Expected Value Exercise 5

Assume that one of two possible outcomes will follow a decision. One outcome yields a $75 payoff and has a probability of 0.3; the other outcome has a $125 payoff and has a probability of 0.7.

In this case the expected value is _______?

  1. EU = (0.3 x 75) + (0.7 x 125) = 110

  2. EU= pr(one outcome)(outcome)+pr(other outcome)(other outcome)
    EU= (0.3x$75)+(0.7x$125)
    EU= 22.5+87.5
    EU= 110

  3. 1st probability outcome yields a %75 payoff with 0.3 probability
    2nd probability outcome yields a $125 payoff with 0.7 probability

    expected value/EV : (1st Pr) (1st payoff) + (2nd Pr) (2nd payoff
    EV : (0.3)($75)+(0.7)($125) = 22.5 + 87.5 = $110

    in this case, the expected value is $110

  4. pak saya ulang ya, biar lengkaaap wakakak :D

    OUTCOME 1 :
    probability = 0.3 , payoff =75

    OUTCOME 2:
    probability = 0.7 , payoff = 125

    EV = (Pr1 x X1) + (Pr2 x X2) =
    (0.3 x 75) + (0.7 x 125) = $110

  5. Known :
    First possible outcome = $ 75
    Probability First possible outcome = 0.3
    Second possible outcome = $ 125
    Probability Second possible outcome = 0.7
    Solutions :
    Expected Value = (First possible outcome ) ( Probability First possible outcome) + ( Second possible outcome ) (Probability Second possible outcome )
    Expected Value = ( $ 75 * 0.3 ) + ( $ 125 * 0.7 )
    = $ 22,5 + $ 87,5
    = $ 110
    So the expected value is $ 110

  6. Diketahui
    outcome (1) $75, outcome (2) $ 125
    Probability
    P1 = 0,3
    P2 = 0,7

    PENYELESAIAN:
    E(v) = (0.3 x 75)+(0.7 x 125)
    = $ 110
    the expected value is $110
