Rules for Discrete Distributions (binomial...)

Question 1

P(at most “r”)

Answer 1

P(x ≤ r)

binomcdf (n,p,r)

Question 2

P(at least “r”)

Answer 2

P(x ≥ r)
1 - P(x ≤ (r-1))
1 - binomcdf (n,p,(r-1))

Question 3

P(more than “r”)

Answer 3

P(x > r)
1 - P(x ≤ r)
1 - binomcdf (n,p,r)

Question 4

P(less than “r”)

Answer 4

P(x

Question 5

P(less than “t” and at least “r”)

Answer 5

P(x
