Seeds are often treated with a fungicide for protection in poor-draining, wet environments. In a small-scale trial, six treated seeds and seven untreated seeds were planted in clay soil and the number of plants emerging from the treated and untreate seeds were recorded. Suppose the dilution was not effective and only four plants emerged. Let x represent the number of plants that emerged from treated seeds. (Round your answers to four decimal places.) (a) Find the probability that x = 4. (b) Find P(x s 3). (c) Find P(2 ≤ x ≤ 3).
