Note - this program does not work in all cases, such as biCDf (use the builtin binomialCDf instead). Answers should be tested by the user.
discrete(”f ”, x, l, u, h)
- f is an expression in terms of x, enclosed in ” ”
- x is a variable name
- l is the x-value of the starting point
- u is the x-value of the ending point
- h is the step size
Returns a matrix with x-values in the left column and f-values at the corresponding x-values in the right column, for discrete values of x with step size h in the domain [l,u].
Example
\(X \sim \mathrm{Bi}(n, 0.1)\). Find the least \(n\) such that \(\mathrm{Pr}(X \geq 2) \geq 0.5\). (2021 Methods Exam 2 Section A Question 17)
