- The calculator warns that its independent-trial model does not fit a deck whose cards are removed.
Field notes
The calculator asks for n, p, and k, and the page says it uses logarithms for larger trial counts to avoid factorial overflow. Its stated boundary is important: independent repeated trials do not describe a deck after cards have been removed. The adjacent table compares abstract models and supports sorting from its column headings; the homepage says neither tool sends data to a server.
