TI-36X Pro—Replace the batteries or just get a new one?

[lrdheat]

Haven't checked, but think I misunderstood the trial limit from o through 41 trials on binomial pdf/cdf's that the 36X Pro manual refers to what can be asked for display in a table form (related to # data points allowed for statistical data). If this is so, the 30X Pro MathPrint likely has a 50 trial limit. On both machines, there is no small limit on "n" number of trials as to calculating probability of "x" successes given "y" probability of success on a given trial.
