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 ≥ 12)
If λ = 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?
For a normal distribution with a mean of 7.5 and a vaiance of 9, find the following probabilities:
a. P(x ≥ 8.5)
b. P(x ≥ 6.5)
c. P(x ≥ 9.5)
d. P(3 ≤ x ≤ 5.5)
