Answer #1

Answer : Correct Option is (D.)89.44%

Calculations

Z = (Cash Flow - Mean) / Standard Deviation

= (11000 - 16000) / 4000

= -1.25

Z value lower than -1.25 is 0.1056

Therefore Probability of Cash Flow lower than 11000 is 0.1056 or 10.56%

Probability of Cash Flow Higher than 11000 is 0.8944(1- 0.1056) or 89.44%
