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

• You should have a?GDC?that can calculate?Poisson probabilities
• You want to use the "Poisson Probability Distribution" function
  • This is sometimes shortened to PPD, Poisson PD or Poisson Pdf
• You will need to enter:How do I calculate P(a?≤?X?≤?b):?the cumulative probabilities for a Poisson distribution??

• You should have a?GDC?that can calculate?cumulative Poisson probabilities

How do I find probabilities if my GDC only calculates P(X?≤?x)?

What if an inequality does not have the equals sign (strict inequality)?
