Compare exact, cumulative and interval event counts
Enter separate formulas in E2:E6. B2 is the fixed number of independent trials, B3 the same event probability in every trial and B4 an exact count. E2 is P(X=B4); E3 is P(X<=B4); E4 is P(X>=B7); E5 is P(B5<=X<=B6), including both endpoints; E6 is the expected count. Keep probabilities as unrounded proportions. Preserve small nonzero tails rather than rounding them to zero.
The answer cells begin blank. Enter a reusable formula and check it against the published practice datasets. Hints and the solution are available when you choose them.
Practice stays on this device. No worksheet data is uploaded.
A checkpoint records a fresh check of every dataset. This attempt tracks built-in hints, solutions, steps and worked examples; it does not establish independent authorship.
Help recorded: none of these built-in aids opened.
