Your friend approaches with three, fair 5-sided dice (labeled 1 to 5). You get to roll them and your friend gives you money base
k0ka [10]

Answer:

$1.68 per match

Average Fee = $1.69

Step-by-step explanation:

Given:

- Earnings for all 3 different number = $ 1

- Earnings for 2 same number = $ 2

- Earnings for 3 same number = $ 6

- Five sided fair dice = 3

Find:

- Expected pay-out

- What fee charged per match for 10 cent income

- Reason for change to new match

Solution:

- Construct a probability distribution table, where X: payout per match

            X               $1                    $2                    $6

          P(X)           0.48                 0.48                0.04

Case X = $1 :          _    _   _   All three different numbers

     No.outcomes    5 * 4 * 3 = 60

     Total outcome  5 * 5 * 5 = 125

Hence, P(X= $ 1) = 60 / 125 = 0.48

Case X = $2 :          S    _   S   two numbers are same

     No.outcomes  = 5 * 4 * 1 = 20 per combination

     Total combinations = S _ S + S S _ + _ S S = 3

     Total outcome = 3 * 20 = 60

Hence, P(X= $ 2) = 60 / 125 = 0.48              

Case X = $6 :          S    S   S   two numbers are same

     No.outcomes  = 5 * 1 * 1 = 5 per combination

     Total combinations = 1

     Total outcome = 5 * 1 = 5

Hence, P(X= $ 2) = 5 / 125 = 0.04    

           

- Expected Payout E(X):

      E(X) = 1*0.48 + 2*0.48 + 6*0.04 = $1.68 per match

- To earn $0.01 on average the fee of match is:

      Fee_avg = E(X) + $0.01 = $1.69

- With this new plan your friend would loose less. The expected payout of a match is $1.68 for which the probability X < $ 2 is around = 0.48. However, to gain a $2 or higher P ( X > 2 ) = 0.48 + 0.04 = 0.52. Hence, the week-payout for X > 2 is greater than 7*2 = $14. So probability of week's payout to be $14 is higher than to be $ 11.76 as per average pay per day.
