The question, in short

Using a partly filled two-way table for 120 customers choosing chocolate, strawberry or vanilla ice cream in a cone or tub, fill in the missing cells and work out the chance a randomly chosen customer had a vanilla cone.

Summarised in our own words. Use the official paper for the exact wording and the diagram.

Part (a) · 3 marks

Fill in every empty cell of the two-way table using the row and column totals given.

  1. 1Strawberry cones = 78 − 16 − 22 = 40; chocolate tubs = 23 − 16 = 7
  2. 2Total tubs = 120 − 78 = 42; vanilla tubs = 42 − 7 − 14 = 21
  3. 3Strawberry total = 40 + 14 = 54; vanilla total = 22 + 21 = 43
  4. 4Table: cones 16, 40, 22, 78; tubs 7, 14, 21, 42; totals 23, 54, 43, 120

Answercones: chocolate 16, strawberry 40, vanilla 22, total 78; tubs: chocolate 7, strawberry 14, vanilla 21, total 42; totals: chocolate 23, strawberry 54, vanilla 43, overall 120

Part (b) · 2 marks
