Random Experiments and Events starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Random Experiments and Events.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

Define a sample space in the context of random experiments.
Describe what is meant by 'equally likely outcomes' in a random experiment.
