Explanation / Answer

Answer

Mean = -2 and variance = 4, so standard daviation = 2.

In order to find Pr(Y<-5). Lets convert it into standard normal form which is given:

Pr(Z < (-5 - (-2))/2) = -3/2 = Pr(Z < -1.5)

hence We have to calculate Pr(Z < -1.5). For that Lets use standard normal table.

From Standard Normal Table we get, Pr(Z < -1.5) = 0.06681.

Hence, Pr(Y<-5) = 0.0668
