Question

If Z has a standard normal probability distribution, find P(Z > −0.75).

Answer 1

Given that Z has a standard normal probability distribution, you need to find the following Probability:

$P(Z>-0.75)$

Therefore, you can find it using the Standard Normal Distribution Table.

By symmetry, you can determine that:

$P(Z>-0.75)=1-P(Z<-0.75)$

Using the Standard Normal Distribution Table (Left Tail), you get that:

$P(Z<-0.75)\approx0.2266$

Therefore:

$P(Z>-0.75)=1-0.2266\approx0.7734$

Hence, the answer is:

$P(Z>-0.75)\approx0.7734$
