LO: To construct a single-step experiment
- How to construct an experiment
- How to construct a tally table to collect data
- that sample spaces can be constructed for single-step experiments
- I can construct a sample space for single-step experiments..
A single-step experiment means a trial using only 1 step.
For example, rolling a die once then recording the result or flipping a coin once is a single-step experiment.
A multi-step experiment means that multiple (more than one) trials are used.
For example, rolling a die then flipping a coin. Or picking the winner and 2nd place finisher in the Melbourne Cup.
The sample space of an experiment is a list of the possible outcomes.
For example, the sample space for the outcome of rolling a die would be 1,2,3,4,5 and 6. The sample space for the outcome of flipping a coin would be heads or tails.
Equally-likely outcomes are situations that have a 50/50 chance (50%) of happening.
For example, rolling a die and seeing whether it lands as an odd or even number is an equally-likely outcome because there is an equal chance of it landing odd (1,3 or 5) compared to landing even (2, 4, or 6). Flipping a coin and seeing whether it lands heads or tails is also an equally-likely outcome.
