My answer:

each dice has these 6 numbers

1,2,3,4,5,6

the even out of all of the numbers are

2,4,6

The others are odd (obviously)

1,3,5

So 1/2 are odd.

1/2 of 60 is the number of times it would get even numbers,

1/2 of 60=1/2 times 60=30

My prediction was 30!

Answer 2

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
