This is our probability density function for q1. And notice, it really spikes close to 0, and that makes sense, because if you're sampling just once from this standard normal distribution, there's a very high likelihood that you're going to get something pretty close to 0. And then if you square something close to 0, remember, these are decimals, they're going to be less than 1, pretty close to 0, it's going to become even smaller. So you have a high probability of getting a very small value. You have high probabilities of getting values less than some threshold, this right here, less than 1 right here, so less than 1 half. And you have a very low probability of getting a large number. I mean, to get a 4, you would have to sample a 2 from this distribution, and we know that 2 is, actually, it's 2 variances, or 2 standard deviations from the mean.
