8 points are spaced around at intervals of one unit around a 2 x 2 square as shown. If 2 of the 8 points are chosen at random, what is the probability that they are more than one unit apart?
+1005 Think of it this way. You pick any spot, and you have 2 points to either sides that are 1 unit away.
thus we have 7-2 /7 = 5/7 probability
if you don't understand anything feel free to ask!
+738 i think what hugo meant was \(\dfrac{7-2}{7}=\dfrac{5}{7}\text{ probability}\)
+1005 Thanks for clarifying, loki.
That is indeed what I meant.
(oops next time I'll do parentheses!)
