I think the correct answer is 4.2
The total number of marbles
=19+11
=30
The number of small green marbles
=11-6
=5
(we don't need to caculate the total number of green marbles here because it doesn't matter whether the large marbles are green or not)
The probability of marble selected is large or green
=19+5/30
=24/30
=12/15
hope it helps ^^
