Two Processes (A, B) are put together to make Process C. What is the probability that the total time is greater than 8.75 hours?

Process A: Average = 3, Std. Dev. = 0.60

Process B: Average = 4.5, Std. Dev. = 0.80

Average (A,B) = 7.5

Std. Dev. (A,B) = sqrt[(0.6)^2 + (0.8)^2] = 1

Z = (8.75-7.5)/1 = 1.25

Z(1.25) = 0.895

Area to the right is 10.5% (1-.895)
