# Statistics/Probability Theory Quiz .1|| Random Variables

Statistics/Probability Theory Quiz.1(MCQs) for your online exam preparation. All multiple choice questions (MCQs) according to your exam syllabus. Here, you can solve all important (mcq) on the topic random variables. Other questions about fluid body and types of fluid, real number system, basic’s of matrices, roots and bisection method.

For random variables, we can discuss types of random variables as well as discrete and continuous random variables, variance, qualitative variables, quantitative variables, probability density function. The end result
Discrete and continuous variables are the two types of random variables. The key distinction between the two groups is the range of possible values for each variable. Furthermore, the type of (random) variable determines the procedure for determining a probability distribution function.
