Answer 1

The 2 red marbles plus 6 yellow and 5 green equal 13 total marbles.

A) There are 2 red marbles out of the total number so 2/13 or about 15.4%

B)The colors that are not yellow are red and green. 2 Red+5 Green=7. 7/13 or about 53.8%.

C)Same as B

D)The only color not red or green is yellow. There are 6 yellow so 6/16 or 46.2%.

Hope this helps :-)
