Probability quiz. Event not happening. KS3 statistics. 2 little quizzes giving the probability of events and students have to say the probability of that event not happening. I use the multiple choice one at the start of the lesson so we can talk about it, then the timed quiz with answers at the end of the lesson as a plenary. Hope you find them useful
