Need help calculating the:

- Variance and -

-Standard deviation for the pipeline

Total profit for duration (in billions) $ 2,013.38

Expected Profit for Pipeline (in billions) $ 1,693.38

Assume there is a 10% probability of the pipeline leaking, with an expected liability of $3.2 billion which will be deducted from total profit. There is a 90% probability the pipeline will not leak.
