Binomial Cumulative Distribution Function
Computes the cumulative probability for a discrete binomial distribution with n trials and success probability p.
binomCdf(n,p): Returns a list of values P(0 ≤ X ≤ k) for k = 0,…,n.
binomCdf(n,p,upperBound): Computes P(0 ≤ X ≤ upperBound).
binomCdf(n,p,lowerBound,upperBound): Computes P(lowerBound ≤ X ≤ upperBound).
If lower and upper bounds are lists, returns a list of the corresponding probabilities.

Binomial distribution
The binomial probability function can be defined using the binomPdf command 5: Probability > 5: Distributions > A: Binomial Pdf.... To calculate the probability for a range of values, you can use a sum or the guided binomCdf command 5: Probability > 5: Distributions > B: Binomial Cdf..., which evaluates the sum for you.
