Experimental probability at a glance
Experimental probability, also called relative frequency, is the probability of an event occurring based on previous events. This is useful when we don’t know the theoretical probability of an event occurring. For example, a biased spinner has three possible outcomes: red, green, and blue. We do not know the probability of each outcome but when we spin the spinner 100 times, it lands on green 17 times. The experimental probability of landing on green is 17 out of 100.
As we increase the number of trials in our experiment, the accuracy of the theoretical probability improves, and the theoretical and experimental probabilities become more similar.
Looking forward, students can then progress to additional probability worksheets, for example the Venn diagram worksheet, the mutually exclusive events worksheet, or the probability tree diagram worksheet.
For more teaching and learning support on probability our GCSE maths lessons provide step by step support for all GCSE maths concepts.
Do you have students who need additional support?
With Third Space Learning's secondary maths tutoring programmes, students in Year 7-11 receive regular one to one maths tutoring to address gaps, build confidence and boost progress.
"My confidence in the tutoring is high. We've had some phenomenal results. I even had one girl get a Grade 8 this year; she came to every tutoring session."
