These University probability and random variables multiple choice questions check your understanding of probability and random variables with 10 questions for pupils aged 18-19. Each question has four answers, and the right one is explained as soon as you choose.
University probability and random variables multiple choice questions: the 10 questions
If \(A,B\) are independent, \(P(A\cap B)=\)
\(\operatorname{Var}(2X)=\)
For \(B(n,p)\) the mean is
For \(\text{Po}(\lambda)\) the variance is
\(\Phi(0)=\)
\(P(A|B)\) equals
\(X\sim N(\mu,\sigma^2)\): standardised variable is
Mutually exclusive events with \(P(A)>0\), \(P(B)>0\) are
\(\binom52=\)
Poisson approximates binomial when
How to use these University probability and random variables 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 and random variables lesson.
Finally, practise more with the probability and random variables 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.
