variables needed: 
drunkard position 
roll average home 
count pub count 
roll count

loop 2 to 7 (starting points)
	set home and pub count to 0
	set roll average to 0
	loop 500 tests per starting point
		set roll count to 0
		set drunkard position to current starting point
		loop until drunkard reaches either home or pub, or some max iteration count 
			generate a random number
			if random < 2/3 then
				drunkard heads towards pub (pos = pos - 1) 
			else
				drunkard heads towards home (pos = pos + 1)	
			end if
			increment number of rolls for this test
			if drunkard is at pos 8 then
				drunkard is home (increment home count for this starting point)
				exit test
			else if drunkard is at pos 1 then
				drunkard at pub (increment pub count for this starting point)
				exit test
			end if
		end loop
		calculate average rolls
	end loop
	display statistics for this starting point
end loop
