The total number of marbles in the picture is 14.
The number of yellow marbles is 5.
Recall that the probability of an event is the ratio of the number of favorable outcomes to the total number of possible outcomes.
It is required to find the probability of picking a yellow marble.
Hence, the number of favorable outcomes is 5, and the number of possible outcomes is 14.
The required probability is, therefore:
The answer is 5/14.
