Answer the following questions. ​(a) The random variable x is distributed​ normally, with x~N(80,100) Find the probability that x is greater than 90. x >90. ​(b) Find P(x<85). ​(c) Find P(76<x<84).

I put the answer to part a) as 0.51^7 which gave me answer of 8.9741 to 4 dp. For part B your working out gives an answer of 0.049 to 4 dp is this correct?
