The probabilities for the standard normal random variable are (a) P(Z > 1.47) = 0.070781 and (b) P(Z > -0.6) = 0.72575

Finding the probabilities for the standard normal random variable

From the question, we have the following parameters that can be used in our computation:

(a) P(Z > 1.47)

(b) P(Z > -0.6)

For a standard normal Distribution, we have that

Mean = 1

Standard deviation = 0

Using the Normal Distribution Table. we hae the following readings

(a) P(Z > 1.47) = 0.070781

(b) P(Z > -0.6) = 0.72575

Hence, the probabilities are (a) P(Z > 1.47) = 0.070781 and (b) P(Z > -0.6) = 0.72575
