Answer:

1. 40 lawns

2. 40 washed cars

3. 20 lawns, 20 washed cars

4. 25 lawns mowed, 25 washed cars

Explanation:

In the given question,

A) When all three spend all their time mowing lawns that is

Kevin= 2 X 10 hrs = 20

Rajiv = 1 x 10 hrs = 10

Yakov = 1 x10 hrs = 10

Total mowed lawns will be= 20 +10 + 10 = 40 lawns.

B) When all three spend their time washing cars

Kevin =  1 x 10 hrs = 10

Rajiv = 1 x 10 hrs =10

Yakov = 2 x 10 hrs = 20

Total cars washed= 20 +10 + 10

C) when all three people spend their half time on each activity

Kevin  = 2 x 5 hours = 10

Rajiv =  1 x 5 hrs = 5

Yakov1 x 5 hrs = 5

Total lawn mowed will be= 10 + 5 + 5 = 20 therefore time spent on car washing will be 20 hrs.

D) Time on the mowing of the lawn will be =

Kevin =  2 x 5 hrs = 10

Rajiv = 0

Yakov = 1 x 10 hours = 10

Time on the washing of the car will be 20 hrs

Kevin = 1 x 5

Rajiv =  1 x 10

Yakov = 0

Total time = 15 hrs

ou are given 6 to 1 odds against tossing three heads with three coins, meaning you win $6 if you succeed and you lose $1 if you
yuradex [85]

Answer:

EV = $-0.125

For one game, the outcome cannot be predicted, even though you are more likely to lose money.

For 100 games, you are expected to lose about $12.50

Explanation:

Expected value is the sum of the product of all possible outcomes by their payouts. In this case, there are only 2 possible outcomes. You either win by tossing 3 three heads with three coins or lose.

The probability of winning (P(w)) is:

P(w)=0.5*0.5*0.5\\P(h)=0.125

Therefore, the probability of losing (P(l)) is:

P(l)=1-0.125\\P(l)=0.875

The expected value (EV) for the game is:

EV= 6*0.125 - (1*0.875)\\EV = -0.125\\

For one game, the outcome cannot be predicted, even though you are more likely to lose money than win. As for 100 games, since the expected value is negative, you are expected to lose money (about $12.50).
