The question, in short
A six-sided spinner labelled 1 to 6 is spun 50 times with results in a table; use the data to work out relative frequency for 4 and an expected count in 200 spins.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Part (a) · 1 mark
Using the table, calculate the relative frequency for landing on 4.
- 1Frequency of 4 = 9 out of 50 spins
- 2Relative frequency = 9/50
Answer9/50
Part (b) · 1 mark
Using 200 spins, work out the expected number of times the spinner lands on 4.
- 19/50 × 200 = 36
