Hints:
- To find the probability that a binomial variable is exactly equal to a
number x, use:
binompdf(n,p,x) where
n is the sample size, p
is the probability of success.
- To find the probability that a binomial variable is less than or equal
to a number x or at most
x, use: binomcdf(n,p,x).
- To find the probability that a binomial variable is less than a number
x, use: binomcdf(n,p,x-1).
- To find the probability that a binomial variable is greater than to a
number x, use the rule of complements:
1 - binomcdf(n,p,x).
- To find the probability that a binomial variable is greater than or
equal to a number x or at least
x, use the rule of complements:
1 - binomcdf(n,p,x - 1).
