How do I calculate, P(X = x)?the probability of a single value for a binomial distribution?

• You should have a?calculator?that can calculate?binomial probabilities
• You want to use the "Binomial Probability Distribution" function
  • This is sometimes shortened to BPD, Binomial PD or Binomial Pdf
• You will need to enter:

How do I find P(X ≥ x)?

• You might be lucky enough to have a calculator that has lower and upper bounds:
  

  How do I find? P(a ≤ X ≤ b)??

• You might be lucky enough to have a calculator that has lower and upper bounds:
  • Use?a?for the?lower?bound and?b?for the?upper?bound
  • Otherwise, you will need some extra identities
