So this one here is clearly a continuous random variable. Let's think about another one. Let's say that random variable Y, instead of it being this, let's say it's the year that a random student in the class was born. Random student in a class was born. Is this a discrete or a continuous random variable? Well that year, you literally can define it as a specific discrete year. It could be 1992 or it could be 1985 or it could be 2000 and 2001.
