a) X ~ N(10, 0.25)

Find P( > 10.25) where n = 10

Find x such that P( > x) = 0.05 where n = 10

b) X ~ N(20.2, 4)

Find P( < 19) where n = 20

Find x such that P( < x) = 0.85 where n = 20

If someone could do a) as an example I should be able to do b. Also the are supposed to be capital X's with the hat on top.

Thanks in advance.
