Answer:
when rolling a die you can end up getting 6 possibilities all together.
the number of even numbers in a die is 3.
therefore in the first throw you have a possibility of getting an even number at 0.5 or 50%.
and in the second throw you have a possibility of getting an even number at 0.5 x 0.5 which is 0.25 or 25%.
Hope this helps.
