Step-by-step explanation:
Given that one of the wagers in the game of roulette is to place a bet that the ball will land on a black number.
Probability will be 18/38 for black and red and 2/38 for green
We have
Colour Black Red Green Total
Number 18 18 2 38
Bet amt. 7 7 7
Win amt. 7 0 0
Net win 0 -7 -7
Prob 18/38 18/38 2/38
Netwin*p 0 -126/38 -14/38
Expected value of win = -140/38 = -3.68
(15 - 3x^2)!
Just find the square root of 225 and 9. It's 15 and 9! However, make sure to add the - sign because it's -9x.
Hope that helps!

Answer:
The value for the original mean = 32
Step-by-step explanation:
Here, we want to calculate the original value of the mean.
Let the number of samples be n
Mathematically;
mean = Total value/n
Now, we added 8 to each of values; total value added = 8 * n = 8n
Now, for the new mean of 40; we have
(Total value + 8n)/n = 40
Total value + 8n = 40n
Total value = 40n -8n
Total value = 32n
kindly recall from the beginning of the solution;
mean = Total value/n
mean = 32n/n
mean = 32
So the original value of the mean is 32
