I actually got all 4 in the final act, was surprised to see it happen As a Maths student I guess I could try to crank up my rusty probability and statistical skills.So, the chance to get AT LEAST 18 out of 24 heads...Means we add the probabilities of getting 18, 19, 20, 21, 22, 23, 24 heads (this is simple to set up since we just have a 0,5 chance for either heads or tails to happen).So it looks as follows...Yeah, about 1% chance sounded about right
