6.44

The area from 110 to 110.5 is 0.25. From Table 6.3, z =

0.67

 

 

            Probability of error greater than 1 Volts:

           

           

            From the normal distribution curve (Table 6.3) for

            z = 1.33   P(z) = 0.4082

 

 

for error greater than 111 or less than 109 (1101)

we will have:
