Agree. Better simply to say simply that in any large ensemble of N outcomes, where 60% will be H, the outcomes can be partitioned into groups that are totally fair (H=T) and totally biased (all H.). The fair partition will be N x 2 p(T) in size.
The blue crescent is made up of a semicircle and a quarter circle (of a larger circle). If the width of the figure (diameter of the semicircle) is 1, what is the area of the crescent?
Place a point P at coordinates (6, 7) in a square with diagonal vertices (0, 0) and (12, 12).
From P draw lines to the vertices and perpendiculars to the sides.
This defines eight triangles that meet at P.
Ignoring permutation of identical pieces, how many other ways can these triangles form a square?
