Find the following probabilities. It may help to sketch the pdf for Standard Normal Distribution
and shade in the area that corresponds to the probability of interest.
1) Z ~ Norm(0, 1), find Pr(Z ≤ 1.78) 
2) Z ~ Norm(0, 1), find Pr(Z > 1.96) 
3) Z ~ Norm(0, 1), find Pr(-2.34 ≤ Z < 1.45) 
4) Z ~ Norm(0, 1), find Pr(Z < -0.67) 
5) Z ~ Norm(0, 1), find Pr(Z = 2.3) 
6) Z ~ Norm(0, 1), find Pr(Z ≥ -2.98) 

Do the same for the following below. Note however that they are no longer Standard Normal
Distributions.
7) X ~ Norm(266, 16^2), find Pr(X < 200) 
8) X ~ Norm(-2, 5^2), find Pr(-4 < X < -3) 
9) X ~ Norm(-2, 5^2), find Pr(X = -3) 
10) X ~ Norm(64.4, 2.4^2), find Pr(|X| > 70)
