- Pascal( <Number of Successes>, <Probability of Success> )
- Returns a bar graph of a Pascal distribution.
- Parameters:
- Number of Successes: number of independent Bernoulli trials that must be successful
- Probability of Success: probability of success in one trial
- Pascal( <Number of Successes>, <Probability of Success>, <Boolean Cumulative> )
- Returns a bar graph of a Pascal distribution when Cumulative = false.
- Returns a graph of a cumulative Pascal distribution when Cumulative = true.
- First two parameters are same as above.
- Pascal( <Number of Successes>, <Probability of Success>, <Variable Value>, <Boolean Cumulative> )
- Let X be a Pascal random variable and v the variable value.
- Returns P( X = v) when Cumulative = false.
- Returns P( X ≤ v) when Cumulative = true.
- First two parameters are same as above.
- Note: This command also works in the CAS View.
- Example:The number of independent Bernoulli trials that must be successful is n = 1, the probability of success in one trial is p = \frac{1}{6}, the variable value is v = 2 and "Cumulative" = false.
Pascal(n, p, v, false)
yields 0.12 in the Algebra View and 25/216 in the CAS View.
