Sample Space Diagrams
Maths: Edexcel IGCSE Higher, topic 6.3.5
Two Way Table
A two way table is a type of sample space diagram.
Sample space
- The sample space of events is all of the possible outcomes of the events.
- The sample space of throwing a head or tails when flipping a coin twice can be written as: (H, H), (H, T), (T, H), (T, T).
Shows all outcomes
- A two way table shows the outcomes of two events.
- The outcomes of one event label the rows and the outcomes of the second event label the columns.
- The overall outcome can then be written in for each combination.
Two way table - example
- The two way table for the sum of two dice rolls is shown above.
