What this AA SL binomial distribution worksheet covers

Modelling the number of successes in a fixed number of independent trials, with full use of the GDC distribution functions. The questions follow the order of the AA SL syllabus for Topic 4 (Statistics & Probability) and are graded in three bands — routine practice, exam-standard, and the harder multi-step questions that separate a 6 from a 7.

Identifying when the binomial model applies
P(X = k), P(X ≤ k) and P(X ≥ k) on the GDC
Expected value np and variance np(1 − p)
Inverse problems: finding n or p from a given probability
Exam tip for this topic. Write the distribution as X ~ B(n, p) and the exact probability statement before giving the GDC value.

How to use it

  1. Do the first band without the AA SL formula booklet, then check which formulas you had to look up — those are the ones to memorise.
  2. Time the second band at roughly 1.2 minutes per mark, the pace of Paper 1 and Paper 2.
  3. For the third band, compare your method with the matching questions in the AA SL question bank; if you want this set marked, send it to Mr Ahmad.
