Cumulative Probabilities

• How do you calculate P(X<5) using your calculator?

  P(X_<4)
• Remember calculators can only do smaller than or equal to when finding cumulative probabilities
• How do you calculate P(X>3) using your calculator?

  1 - P(X_<3)
• How do you calculate the cumulative probability of P(6<x_<10)?

  P(X_<10) - P(X_<6)
