These Year 9 probability multiple choice questions check your understanding of probability: sample spaces and Venn diagrams with 10 questions for pupils aged 13-14. Each question has four answers, and the right one is explained as soon as you choose.
Year 9 probability multiple choice questions: the 10 questions
A fair die is rolled. The probability of a number greater than 4 is:
P(A) = 0.35. P(not A) is:
How many outcomes are in the sample space for two coins?
A β© B means:
A βͺ B means:
n(A) = 10, n(B) = 8, n(A β© B) = 3. n(A βͺ B) =
Probabilities of all outcomes add up to:
P(total 7) with two dice is:
Which event is impossible?
A spinner is spun 80 times with P(blue) = 3/8. Expected blues:
How to use these Year 9 probability multiple choice questions
First, read each question carefully before you look at the four answers. Then work the answer out on paper, so that you do not simply guess. After that, read the explanation, even when you are right. If you score less than 7 out of 10, go back to the probability: sample spaces and Venn diagrams lesson.
Finally, practise more with the probability: sample spaces and Venn diagrams worksheet and the quiz. Moreover, all the pages of this chapter work together, so you can move between them at any time. For example, many pupils read the lesson on Monday, practise on Wednesday and test themselves on Friday.
