Calculating Binomial Probabilities (AQA A-Level Mathematics): Flashcards

Running total

$P(X \leq n)$

$1 - P(X \leq 6)$

Binomial CD

Binomial PD

For cumulative probability $P(X \leq n)$

For exact probability $P(X = n)$

$P(X \leq b) - P(X \leq a-1)$

Convert to a calculation using $\leq$

$P(X \leq 7) - P(X \leq 1)$
