How to Declare a variable that stores the cumulative sum java?

In Java:You declare the variable like this:int sum;If you want to include decimals, change this to:double sum;To store an initial value, just use the assignment operator:sum = 0;You can combine this with the declaration:double sum = 0.0;To add something to the variable, for example the value of a variable called "x", use one of the following:sum = sum + x;sum += x;In Java:You declare the variable like this:int sum;If you want to include decimals, change this to:double sum;To store an initial value, just use the assignment operator:sum = 0;You can combine this with the declaration:double sum = 0.0;To add something to the variable, for example the value of a variable called "x", use one of the following:sum = sum + x;sum += x;In Java:You declare the variable like this:int sum;If you want to include decimals, change this to:double sum;To store an initial value, just use the assignment operator:sum = 0;You can combine this with the declaration:double sum = 0.0;To add something to the variable, for example the value of a variable called "x", use one of the following:sum = sum + x;sum += x;In Java:You declare the variable like this:int sum;If you want to include decimals, change this to:double sum;To store an initial value, just use the assignment operator:sum = 0;You can combine this with the declaration:double sum = 0.0;To add something to the variable, for example the value of a variable called "x", use one of the following:sum = sum + x;sum += x;

What does define mean in math terms?

The mean is sometimes also known as the arithmetic average. For a finite number of observations, it is he sum of their values divided by the total number. It can also be described as the expected value of a variable. If a discrete numerical variable X can take the values x, then the mean is the sum [x*pr(X = x)] where the summation is over all possible values of x. For a continuous variable, replace the summation by integration.

How do you compute expected value from random discreet variable?

Follow these steps:Find all the values that the random variable (RV) can take, x.For each x, find the probability that the RV takes than value, p(x).Multiply them: x*p(x).Sum these over all possible values of x.The above sum is the expected value of the RV, X.
