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

• You should have a?GDC?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 calculate P(a?≤?X?≤?b):?the cumulative probabilities for a binomial distribution??

• You should have a?GDC?that can calculate?cumulative binomial probabilities
• • The 'n' value - the?number of trials
  • The 'p' value - the?probability of success

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

• To calculate P(X?≤?x) just enter?x?into the cumulative distribution function
• What if an inequality does not have the equals sign (strict inequality)??

• For a binomial distribution (as it is discrete) you could?rewrite all strict inequalities?(< and >) as?weak inequalities?(≤ and ≥) by using the identities for a binomial distribution
