If all of the grains and vegetables were accidentally displayed together without a sticker or label to mark their origin, what is the probability that you select a grain or vegetable that is conventional into your grocery basket? First compute for yourself the row (i.e., n₁₊, n₂₊), column (i.e., n₊₁, n₊₂, n₊₃, n₊₄), and overall (i.e., n₊₊) totals, to aid in answering the question.
