I got four instances of this random variable.
And now just is this random notation I'm coming with the two-sided.
But an experiment is every time you run this random event.
A hundred instances of this random variable, average them, plot it.
So in that means I take, literally, four instances of this random variable.
So in this random distribution I made my standard deviation was 9.3.
Now I'm going into all of this random variable business.
This random mutation gave that microbe a protein molecule that absorbed sunlight.
We take a hundred instances of this random variable, average them, plot it.
This random variable, number of heads after 5 flips-- you can't have an infinite number of values here.
We take 10 samples from this random variable, average them, plot them again.
First of all, we know what the expected value of this random variable is.
The expected value of this random variable is n times p, or sometimes people will write p times n.
That literally just means I take 1 instance of this random variable and average it.
We can say this random variable is going to be equal to 1 if it rains tomorrow and it equals 0 if it doesn't rain tomorrow.
Or, since it's a random variable, the expected value of this random variable.
So we take 10 instances of this random variable, average them out, and then plot our average.
And we know what the expected value is, we know the expected value of this random variable is 50.
We just looked at the probability distribution for this random variable, the number of heads after 6 tosses of a fair coin.
Now we don't know the entire covariance. We only have 1 sample here for this random variable.
And we saw if you actually figured out the probability distribution for this random variable you get that nice binomial distribution that looks a little bit.
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.
We could have taken 10 samples from this from this population, you could say, or from this random variable, average them, and then plotted them here.
And your goal is to figure out the probability distribution of this random variable and then once you know the probability distribution then you can figure out what's the probability that 100 cars pass in an hour or the probability that no cars pass in an hour and you would be unstoppable.
If we wanted to know the expected, or if we talked about the expected value of this random variable x, that is the same thing as the mean value of this random variable x.
That the central tendency or you could say, the population mean, of this random variable, or you could say the expected value of this random variable is exactly 3.
But the important thing to realize that there's a finite number of values that this random variable can take on and that's why we have a discreet probability distribution.
