Chapter 6 Part 2 - Binomial and Geometric Probability

In a binomial setting what is used when we are trying to find at most k?

• binomialcdf( n, p, k)

• binomialpdf(n, p, k)

• 1 - binomialcdf(n, p, k)

• 1 - binomialcdf(n, p, k -1)

In a binomial setting what is used when we are trying to find at least k?

• binomialcdf( n, p, k)

• binomialpdf(n, p, k)

• 1 - binomialcdf(n, p, k)

• 1 - binomialcdf(n, p, k -1)

In a binomial setting what is used when we are trying to find more than k?

• binomialcdf( n, p, k)

• binomialpdf(n, p, k)

• 1 - binomialcdf(n, p, k)

• 1 - binomialcdf(n, p, k -1)

In a binomial setting what is used when we are trying to find exactly k?

• binomialcdf( n, p, k)

• binomialpdf(n, p, k)

• 1 - binomialcdf(n, p, k)

• 1 - binomialcdf(n, p, k -1)
