    5.3
    Used the binomial distribution table to callculate the following probabilites for a binomial random variable where n = 20 and p = 0.40
    a. p(x = 10)
    b. p(7< x <12)
    c. P(x &#8805; 12)

    5.29
    If &#955; = 5 and t=2 for a Poisson distribution,
    a. Determine the mean and standard deviation of this Poisson ditribution
    b. What is the probability of three or fewer successes?

    5.45
    For a normal distribution with a mean of 7.5 and a vaiance of 9, find the following probabilities:
    a. P(x &#8805; 8.5)
    b. P(x &#8805; 6.5)
    c. P(x &#8805; 9.5)
    d. P(3 &#8804; x &#8804; 5.5)
