Yes I think it would be way better if both classes have a 50% chance.

- gwd 4y agoIf you flip a coin 30 times you won't get 15 heads and 15 tails. But getting 30 heads in a row would be one in a billion (literally); HN is popular but I doubt there's a billion people going to the site...
- MacsHeadroom 4y agoGetting any combination of flips is one in a billion. HHHHHHHHHHHHHHHHHHHHHHHHHHHHHH and HHTHTHTTTTHTHTHTHTHTHHHTHTHTHTHTH are equally as likely outcomes.
- gwd 4y agoRight, but there is exactly one outcome with all heads, and there are at least millions of combinations with 50% heads and 50% tails. To make it more obvious, let's take just 4 flips. There is exactly one combination with 4 heads: HHHH Whereas all the following will give you 2 heads and 2 tails: HHTT HTHT HTTH THHT THTH TTHH So you're 6x more likely to get 50% heads/tails than 100% heads. Scale that up to 30; the chances of getting 15 heads and 15 tails is not the most common thing but not unusual. The chances of getting all heads is quite rare -- if every human on earth did this test, we'd expect around 7 such instances total.
