Answer 2

count how many are greater than 5

Answer 3

there are a lot, too many for me to write them all but you can count them
then divide that number by \(36\)

Answer 4

i only count 10 less than or equal to 5, leaving the rest 26 greater than 5
that makes it \(\frac{26}{36}\) which you can reduce

Answer 5

is it 1/3?
