Definition of discrete math

Web(i) The key fact here is that the square of, for example, $-2$ is the same as the square of $2$. Thus $g (-2)=8-7=1$ and $g (2)=8-7=1$. We have found an $x$ and a $y$, with $x\ne y$, such that $g (x)=g (y)$. (ii) We give two ways of seeing that $g$ is not onto. Let $y=-10$. We show there is no integer $x$ such that $g (x)=y$. WebAboutTranscript. Discrete random variables can only take on a finite number of values. For example, the outcome of rolling a die is a discrete random variable, as it can only land on one of six possible numbers. Continuous random variables, on the other hand, can take on any value in a given interval. For example, the mass of an animal would be ...
