Event 1: Absolute
It's talking about both marbles, so it doesn't matter which one you get, as long as you pick one of the two from the bag.
Event 2: Less likely
9/20 for only black versus 11/20 for only green.
Event 3: As likely as not
Both have the probability of 8/16 which simplifies to 1/2.
Event 4: Never
No blue marbles.
