    Normal distribution - please help ASAP!

    1) Let X be a normally distributed random variable with a mean of 3 and a standard deviation of 2.3. Use the

    tables provided to calculate the probability that a randomly selected x-value from this distribution has a value

    between 0 and 2.4.

    2) Refer to the normal distribution of question #1. What is P(X=2)?

    -------------------------------

    This is due tomorrow and I've been struggling with it all week. X_X;

    1) Refer to your other thread on the general approach.

    2) For any continuous random variable X, Pr(X = a) = 0. You ought to know this already.
