A useful correction report
Include N, K, n, k and the query mode, then the exact fraction you received and the answer you expected. Explain whether your intended draw returns items, cares about order or uses unequal chances. Those details can change the model rather than reveal an arithmetic error.
You may include a browser name and a short description of an inaccessible control. Do not send private datasets, identity records, payment details or passwords. A reply time is not promised.
The worked guide covers the model, rounding policy and CSV import caveat. Privacy and service disclosures explain what happens if you choose to email. There is no on-site message form or upload feature.
