A
Find the probability that X = 8 in a binomial distribution with n = 20 and p = 0.5.
B
Find the area between 0 and 8 in a uniform distribution that goes from 0 to 20.
C
Find the probability that X = 8 for a normal distribution with mean of 10 and standard deviation of 5.
D
Find the cumulative probability for 8 in a binomial distribution with n = 20 and p = 0.5.
