Seeds are often treated with fungicides to protect them in poor-draining, wet environments. A small-scale trial, involving four treated and four untreated seeds, was conducted prior to a large-scale experiment to explore how much fungicide to apply. The seeds were planted in wet soil, and the number of emerging plants were counted. If the solution was not effective and three plants actually sprouted, compute the following probabilities. (Round your answers to four decimal places.) (a) What is the probability that all three plants emerged from treated seeds?
