Given that Z has a standard normal probability distribution, you need to find the following Probability:
[tex]P(Z>-0.75)[/tex]Therefore, you can find it using the Standard Normal Distribution Table.
By symmetry, you can determine that:
[tex]P(Z>-0.75)=1-P(Z<-0.75)[/tex]Using the Standard Normal Distribution Table (Left Tail), you get that:
[tex]P(Z<-0.75)\approx0.2266[/tex]Therefore:
[tex]P(Z>-0.75)=1-0.2266\approx0.7734[/tex]Hence, the answer is:
[tex]P(Z>-0.75)\approx0.7734[/tex]
