do #7 and #9 please and graph them on a pencil and paper 

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, 162), find Pr(X<200)
8) X~ Norm(-2, 52), find Pr(-4 < X <-3)
9) X~ Norm(-2, 5²), find Pr(X=-3)
10) X~ Norm(64.4, 2.42), find Pr(|X| >70)
