# Mouse Emulation
# ===============
#
# This configuration file emulates a mouse. The left stick controls
# the cursor, the right stick becomes a horizontal and vertical scroll
# wheel, the dpad acts as cursor keys, the start and back buttons
# become forward and back buttons, the guide button escape and LB and
# RB become page up and page down and the face button act as mouse
# button.

Flip a fair coin 100 times—it gives a sequence of heads (H) and tails (T). For each HH in the sequence of flips, Alice gets a point; for each HT, Bob does, so e.g. for the sequence THHHT Alice gets 2 points and Bob gets 1 point. Who is most likely to win?
