Answer:
The elevation of submarine is −1487.5 feet that means the submarine is 1487.5 feet below the sea level.
Step-by-step explanation:
We are given the following information in the question:
A submarine is 1,275.5 feet below sea level.
It dives down 215.5 feet
It rises 125.5 feet.
Finally, the sub dives down another 122.4 feet.
We are given that the sea level is at an elevation of 0 feet.
Elevation of submarine is given by:
The elevation of submarine is −1487.5 feet that means the submarine is 1487.5 feet below the sea level.

Answer:
The expected payoff for this game is -$1.22.
Step-by-step explanation:
It is given that a pair of honest dice is rolled.
Possible outcomes for a dice = 1,2,3,4,5,6
Two dices are rolled then the total number of outcomes = 6 × 6 = 36.
The possible ways of getting a total of 7,
{ (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) }
Number of favorable outcomes = 7
Formula for probability:
So, the possibility of getting a total of 7 =
The possible ways of getting a total of 11,
{(5,6), (6,5)}
So, the probability of getting a total of 11 = =
Now, other possible rolls = 36 - 6 - 2 = 36 - 8 = 28,
So, the probability of getting the sum of numbers other than 7 or 11 = =
Since, for the sum of 7, $ 22 will earn, for the sum of 11, $ 66 will earn while for any other total loss is $11,
Hence, the expected value for this game is
Therefore the expected payoff for this game is -$1.22.
