Comments

T is the number of trials. P is the probability of a success (i.e. of the outcome you're interested in). The program returns the number of successes, and stores the results of the trials in list L₁. The program will erase any previous contents of L₁. You can have at most 999 trials (since this is the maximum capacity of the lists on a TI-83).

Disp and Input are in the PRGM I/O menu.

For and End are in the PRGM CTL menu.

ClrList is in the STAT EDIT menu.

rand is in the MATH PRB menu.

£ is in the TEST (2^nd MATH) menu.

® is the [STO®] key.
