Answer:
53
Step-by-step explanation:
It is a trick question. 6 people to paint 6 walls will take 53. 20 people to paint 20 walls will take 53 minutes.
They are not, because inverse means multiply by -1, therefore, there should be a positive sign in front of 2 and a negative in front of x for G(x) = x - 2
Solution -
The probability of getting 6 from a single roll of a fair dice = 
The probability of getting any other number rather than 6 would be
So when the outcome is 6, then he wins $5 ,otherwise he has to pay $2
So
E(X) = Expectation value =
( ∵ $5 gain so +ve and $2 loss so -ve)
=
∴ So Merrill will lose
