So, p should be close to ½
Just matter of combining like terms
6x - 7 - 11x + x =
(6x + x - 11x) - 7 =
(7x - 11x) - 7 =

Even numbers
so each dice has numbers
1,2,3,4,5,6
the eve numbers are
2,4,6
odd are others
1,3,5
so 1/2 are odd
therefor 1/2 of 60 is how many times it would get even
1/2 of 60=1/2 times 60=30
No not good predicition
my prediction would be 30 tiemes
