    Normal Probability Distributions....

    I am totally lost....

    I changed the problem around a bit, but it is similar in form to this, on my homework.

    How would I go about solving this?

    Thanks,

    the absolute value of something |Z|, is always equal to Z or -Z.

    So
    P(|Z| > 1) = P(Z > 1) + P(-Z > 1)
    ie, the absolute value of Z is greater than one if Z>1, or -Z > 1.

    try applying this to your problem and post again if you are stuck.
