These Year 13 conditional probability and the Normal distribution multiple choice questions check your understanding of conditional probability and the Normal distribution with 10 questions for pupils aged 17-18. Each question has four answers, and the right one is explained as soon as you choose.
Year 13 conditional probability and the Normal distribution multiple choice questions: the 10 questions
\(P(A\mid B)=\)
If \(A\) and \(B\) are independent then \(P(A\cap B)=\)
For \(X\sim N(10,2^2)\), the standardised value for \(X=14\) is
The Normal curve is
About what percentage lies within 2 standard deviations of the mean?
For \(B(100,0.5)\) the Normal approximation has variance
A continuity correction converts \(P(X\ge45)\) to
For continuous \(X\), \(P(X=a)\) is
In a tree diagram, probabilities along a path are
\(Z\sim N(0,1)\). \(P(Z<0)=\)
How to use these Year 13 conditional probability and the Normal distribution 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 conditional probability and the Normal distribution lesson.
Finally, practise more with the conditional probability and the Normal distribution 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.
