Answer:
Expected return for this bet = - $0.0243
Step-by-step explanation:
to find out
the expected return for this bet
solution
we know that Number of slots in the spinner is
Number of slots in the spinner = 0 + 40 = 41 slots
so
P for you winning is here = 
and
Winning amount is = $40
so we can say that
Expected return for this bet is = Winning amount × P (winning) - Cost of bet ...............................1
put here value we get
Expected return for this bet = $40 × - 1
Expected return for this bet = - $0.0243

Step-by-step explanation:
To figure out the variance, subtract 82.5 from the mean, which is 5.5 and then divide by N, which is the value of numbers, (in this case 10) minus 1. The result is a variance of about 9.17. Standard deviation is the square root of the variance so that the standard deviation would be about 3.03.Calculate the mean.
Subtract the mean from each observation.
Square each of the resulting observations.
Add these squared results together.
Divide this total by the number of observations (variance, S2).
Use the positive square root (standard deviation, S).
88, 10 times 8 is 80. both weeks would be 80 + 8. 88
