<span>To begin, there are only two ways to find die values beginning with a 3 that will give a score of greater than 14: (5,6). Moving to a first roll of 4, there are 3 values that will do the same: (4,5,6). A first score of 5 gives four values (3,4,5,6), and a first roll of 6 will give four values, as well (3,4,5,6). This gives a total of 13 out of 36 possibilities that will have a product of greater than 14.</span>

so.. .if we use those 2 points, from the "best fit line"
It would be c2=a2+b2-2ab cos C
1/2 + 1/3 = (3*1)+(2*1) / (2*3) = (3+2)/6 = 5/6
tinha 5/6 de litro
para 1 litro faltam 4/6 de litro
para 3 litros faltam 2 litros e 4/6 de litro ou, simplificando:
4/6 = 2/3, logo, faltam 2 litros e 2/3 de litro.
