Answer:
Answer is D.
Step-by-step explanation:
As rolling a one on a fair die has a probability of 1/6, on average it is likely that a one will be rolled around once every six rolls, therefore the game’s expected value is 0 because in six rolls one roll will yield 50 and the other five rolls -10 each granting a net total of 0.

Answer:
x = 3.8 + 53.6
Step-by-step explanation:
From the info that they gave you, you can tell that the original number is unknown, so that is x. Since Sushil is subracting 3.8, meaning, to get x, you're going to have to do the opposite which is........addition! So, to get x, you have to add 3.8, and 53.6. I hope I make sense!!
Find the total of the 3 CD's by multiplying 13.99 by 3:
13.99 x 3 = 41.97
Now add the tax:
41.97 x 1.04 = 43.65 ( total of 3 CD's with tax.)
Subtract the total of the CD's from the amount you have to find the change:
60 - 43.65 = 16.35
The answer is c. 16.35
