Getting a 5 = 1/6
Getting tails = 1/2
1/6 * 1/2 = 1/12
(1,0) or (2,5) or (3,10)
5-0=5, 10-5=5, and 15-10=5
Take the root of both sides and solve.
c = - 7 sqr root 5
c = -1.258
1/3 = 2/6 = 3/9 = 4/12 = 5/15 = 6/18 = 7/21 = 8/24 = 9/27 = 10/30 = 11/33 = 12/36 = 13/39 = 14/42 = 15/45 = 16/48 = 17/51 = 18/54 = 19/57 = 20/60
You can use any, these are just the smallest to the biggest but any are fine but I would use the first one. Hope I helped. Equivalent is what 3/9 equals to.
