1. The issue with multiplying the probability/rarity of each is they are actually positively correlated -- Taller people have bigger parts (sorry I can't google to confirm on work laptop rn), and Taller people have higher salaries.

2. I've heard a variant of the "rule" (of thumb) that is six 6's . 6 pack abs, 6' tall, 6" below, 6 figures, 6 months (or more) single, 600+ HP car. This is sometimes pushed around by guys doing the very human thing of overweighting their own biologically driven selection criteria biases and assuming women choose the same way as they do. If you're a man reading this remember that women are naturally driven by 2 forces in selection, which are unfortunately called Alpha and Beta by the internet (though they should not connote superior and inferior). You can fit into the other category of being a great partner via connection, father traits (intelligence, support, kindness), being funny (also intelligence), and connecting on shared interests. Thankfully women tend to select from a large bucket of desires, unlike the testosterone driven visual selection that men trend towards which really causes a lot of trouble for women who bring a lot to the table but not "that".
