    Researchers at a pharmaceutical company have found that the effective time duration of a safe dosage of a pain relief drug is normally distributed with mean 2 hours and standard deviation 0.3 hour. For a patient selected at random:

    b) What is the probability that the drug will be effective for 1 hour or less?
    c) What is the probability that the drug will be effective for 3 hours or more?
