Let Xi denote the number of times that outcome Oi occurs in the n repetitions of the experiment.
Function of several real variables - Wikipedia
https://en.wikipedia.org/wiki/Function_of_several_real_variablesIn mathematical analysis its applications, a function of several real variables or real multivariate function is a function with more than one argument, with all arguments being real variables. This concept extends the idea of a function of a real variable to several variables. The "input" variables take real values, while the "output", also called the "value of the function", may be real or complex. However, the study of the complex valued functions may be easily reduced to the study of the re…

It is clear that if W and L vary, area A depends on two variables: width W and length L. Area A is said to be a function of two variables W and L. Example 2 A rectangular solid has width W, length L and height H.
