I have changed the random variable now.
The random variable x plus the random variable y.
Because you can just keep on performing the experiment that generates the random variable.
And the random variable, X, is the number of shots I make.
And then we figured out the different probabilities that the random variable could take on different values.
So if we say that the random variable, x, is equal to the number of-- we could call it successes.
Although, sometimes when you see it formally explained like this with the random variables and that it's a little bit confusing.
The random variables are the functions associated with a real number to each element of a set E.
Let's say I have the random variable a, and I define random variable a to be x minus y.
So the expected value of these squared differences, andthat you could also use the notation sigma squared for the random variable x.
The random variable, the number of heads I get in 5 flips of the coin-- it was equal to 5 factorial divided by n factorial.
Each of the values of probabilities for each of the random variable values-- you can figure them out by using your binomial coefficients.
And this random variable, just to go back to the top,we defined the random variable as the number of cars that pass in an hour at a certain point on a certain road.
So one is is that if I have some third random variable, let's say I have some third random variable that is defined as being the random variable x plus the random variable y.
If we talk about the variance of the random variable x, that is it the same thing as the expected value of the squared distances between our random variable x and its mean.
And the reason why I'm doing this connection is one,to make you see the connection between the random variable and the probability, and the statistics that we talked about earlier.
Which we saw in the last video was the exact same thing as adding everything together and dividing by the number of numbers,except that that method worked with an infinite number of an infinite population what the random variable is.
Although I knew that probability theory was a means of describing such phenomena, I was not satisfied with contemporary papers or works on probability theory,since they did not clearly define the random variable, the basic element of probability theory.
For example, in the theory of probability and mathematical statistics method used to determine the characteristics of a random variable is the standard deviation,which determines the width of the range of values of the random variable.
Now the whole reason why I went through this exercise, kind of the important takeaways here is that the mean of differences right over here-- so I could re-write it as the differences of the random variable is the same thing as the differences of their means.
So this is the distribution of random variable x.
Let's do the same thing for random variable y.
Find the probability function andthe distribution function of the discrete random variable.
So the expected value of our random variable is equal to the sum.
I will now introduce you to the concept of a random variable.
