binompdf( is broken on the TI-83 (tested ROM 1.0200) and TI-86 as well.
On the TI-83 I tested, binompdf(300,0) gives three nonzero elements; element 47 shows 3.4ᴇ-49 but shows more garbage in the stats editor if stored to L1, element 49 shows 4.857494³ᴇ-123, and element 301 shows 1. sum(Ans) fails with ERR:DATA TYPE, and L1(47) fails with ERR:SYNTAX.
The Inferential Statistics add-on for the TI-86 is also broken in pretty much the same way. The corrupted list elements (comprising most of the output of binompdf(300,0)) contain base-hex characters and very large negative exponents. Fortunately this should be easily patchable since it's not part of the ROM.
TI-84 Plus OS 2.43 throws ERR:MEMORY, then hangs, on binompdf(300,0) \ binomcdf(300,0). The TI-83 does not freeze (ERR:UNDEFINED immediately), and the TI-86 throws an ERR:MEMORY with a sluggishly-loading options menu. I have not tested my 83+, but at this point I don't think we need to.
