P(.88<x<1.32)


= 0.096012


rounded to 4 decimals = 0.0960


= about 9.6% or almost 10%


use a z calculator, a calculator with statistics functions, or an online z calculator



P(x>1.6 or x<.24) = 0.64963 = about 65%


rounded to 4 decimals = 0.6496


above assumes a normal distribution.


the problem doesn't show what distribution is involved. So, if it's not normal, there's another ansswer
