George Stagg on Probability mass function of string of heads from weighted coin, 1 month, 2 weeks ago

Saved a checkpoint:

  • Added bullet points to question statement
  • Named some of the gaps
  • Replaced tolerance in part c) into proper precision restriction
  • Removed unnecessary precround from var variable
  • Removed "Bill style" question marks in gap fill parts

Ulrich Görtz on Arithmetics of complex numbers V 5 months, 2 weeks ago

Wants to merge their version, Ulrich's copy of Arithmetics of complex numbers V .

In part d) the expected answer should be {i^rem} not {i^n} because the latter, while "mathematically" the same, leads to floating point number issues when revealing the answers (it shows something like, e.g., "Expected answer 1 - 5047/2104i*10^(-12)" instead of "1"  (in case rem==4).

I hope that this is the appropriate way to submit this comment.
