Use the basic definition of probability -- the ratio of "good" outcomes to all possible outcomes.
When choosing one of these cards, there are 8 good outcomes -- drawing either one of the 2 yellow of one of the 6 green.
The total number of possible outcomes is the total number of cards, which is 2+6+6 = 14.
So the probability of getting a yellow or green when 1 card is chosen is 8/14, or 4/7.
