(For math people: this can be modeled as a hypergeometric distribution with N=48, K=13, n=8, k=0.)
I suspect most people haven’t heard these terms. But they should have studied basic combinatorics in high school, and that’s all it really is. You had a pool of 48 people from whom to choose 8, but you happened to choose them from the specific pool of 35 not up for reelection. So the likelihood of that happening randomly is just 35 choose 8 / 48 choose 8, which is indeed 6.2%.
