Basic Probability Engineering Tripos Part 1A P 4/9 This document is intended as a simple introduction to the subject for those who have not met probability theory as part of their previous maths studies. Probability theory is one of those mathematical topics which is best learnt from seeing and performing a large number of examples. Each new topic Directly or indirectly, probability plays a role in all activities. For example, we may say that it will probably rain today because most of the days we have observed were rainy days. However, in mathematics, we would require a more accurate way of measuring probability. Samples in Probability

Nevertheless, as we will discuss later on, this is not important. Figure 4.2 shows the PDF of $X$. As we see, the value of the PDF is constant in the interval from $a$ to $b$. That is why we say $X$ is uniformly distributed over $[a,b]$. Fig.4.2 - PDF for a continuous random variable uniformly distributed over $[a,b]$. Probability means the possibility that an event will occur. Learn its types, formulas, tree diagram, events, terms used and examples, solved problems along with video lessons.

Solution: Without loss of generality, we assume that the statistical properties of the random variables Xand Y are given by the joint probability density function f XY (x;y) and marginal probability density functions f X(x) and f Y (y).
