No. of fishes (or tools) needed.

n max

Maximum n to be investigated.

ntr

No. of simulation trials (max: from field size).

.Seed

Random (integer) "seed". Iff seed is ≠ 0, simulation is repeatable.

Show values

Shows the values of the graph coordinates.

For samples of sizes n to n max fishes or tools, probabilites are calculated via the Monte Carlo method that the sample contains at least: one fish of each sex; or one tool of each type. (Run time for the base case is ca. 1 s.) An exact solution.xls is given by Feller [1968].
^† Preference is given to the (hopefully correct) BrEng plural fishes, instead of the AmEng fish as used by Carr [1992].
