1. The probability that the project will finish by the end of day 32 .Using
equation 11.7, we find that Z =( 32 − 32 )∕ 2 . 972 = 0. From the Z table

(Table 11.1), we find that

Pr ( T s ≤ 32 )= 0 . 5 = 50 %

See Figure 11.2.

2. The probability that the project will finish by the end of day 34 .

Z =( 34 − 32 )∕ 2 . 972 = 0 . 67

From Table 11.1, we find that

Pr ( T s ≤ 34 )= 0 . 749 = 74 . 9 %

See Figure 11.3.
