Gets us exactly one head? We have this one right over here. What's the probability that our random variable capital X is equal to one? Well, let's see. It's one out of the eight equally likely outcomes. Situation right over here where you have zero heads. That our random variable X is equal to zero? Well, that's this What's the probability, there is a situation ![]() But which of them, how would these relate to the value of this random variable? So let's think about, So there's eight equally, when you do the actual experiment there's eight equally So you could get all heads, heads, heads, heads. Of the different values that you could get when ![]() We'll plot them to see how that distribution is spread out amongst those possible outcomes. So what is the probability of the different possible outcomes or the different possible values for this random variable. ![]() Of a random variable, what we're going to try Voiceover:Let's say we define the random variable capital X as the number of heads we get after three flips of a fair coin.
