A casino features a game in which a weighted coin is tossed several times. The table shows the probability of each payout amount
kkurt [141]

Answer:

The expected payout of the game is $230.46.

Step-by-step explanation:

The given table is

Payout Amount :    $160       $4400      $145000      

Probability         :    0.146       0.024          0.0007

We need to find the expected payout of the game.

The formula for expected payout is

\text{Expected payout}=\sum n_iP(x_i)

where, n is amount and P(x) is probability of that event. The value of n is negative for loss.

Using the above formula we get

\text{Expected payout}=160\times 0.146+4400\times 0.024+145000\times 0.0007

\text{Expected payout}=23.36+105.6+101.5

\text{Expected payout}=230.46

Therefore the expected payout of the game is $230.46.

Joe can clear a lot in 2.5 hours. His partner can do the same job in 7.5 hours. How long will it take them working together?
irina [24]

Answer:

The time required by both persons to complete the work T = 1.458 hours

Step-by-step explanation:

Given data

Time required by Joe to clear a lot T_1 = 2.5 hours

Time required by his partner to clear a lot T_2 = 2.5 hours

Time required by both persons to complete the work by working together

T = \frac{T_1 T_2}{T_1 + T_2}

T = \frac{(2.5)(3.5)}{2.5 + 3.5}

T = 1.458 hours

Therefore the time required by both persons to complete the work T = 1.458 hours
