    Given a normal distribution with ? = 100 and ? = 10, what is the probability that:

    a. X > 75?
    b. X < 70?
    c. X > 112?
    d. 75 < X < 85?
    e. X < 80 or X > 110?
    f. 10% of the values are less than what X value?
    g. 80% of the values are between what two X values (symmetrically distributed around the mean)?
    h. 70% of the values will be above what X value?
