# 5 calculate the area of the WHOLE flag = fly x hoist
there are 7 red stripes.....each strip has an area of 1/13 hoist x fly
there are 7 of them 7 x 1/13 hoist x fly = red area (almost)
BUT 4 of the stripes are shorter....you must subtract the area of the stripes that are missing
width of a stripe x 4 x (Union fly) = area to be subtracted from the red area calculated area above
THEN probability of landing on red = red area/ total area of flag Do you see? go through it slowly and understand each step !
