Matlab as a simulation software that bridges the gap between theory and the actual implementation o
Problem 5.10
In general, if X is a Gaussian RV with mean m and variance 02, we have,
P(X>cx):Q(x_m)
0'
Therefore,

and using the relation P(0 < X < 9) = P(X > 0) i P(X > 9), we have
P(X>7):Q( ):Q(l):O.158
P(0 <X < 9) 7 (2(034) (2(934) ,1
