Fungicides are used to protect seeds in wet environments. To test the effectiveness of a fungicide, twenty seeds were planted wherein ten seeds were treated with fungicide and the other ten were not. The seeds were planted in wet soil, and the number of plants that emerge were counted. If the fungicide was not effective, what is the probability that two out of four plants that emerge are from treated seeds? A.0 B. 0.3750 C. 0.4180 D. 0.5000
