Gce Model Questions Vol1 2018 Agricultural Science Question 35
Practice objective / multiple choice question 35 from the 2018 Gce Model Questions Vol1 Agricultural Science examination.
The occurrence of a particular fungal disease in a crop requires three independent conditions: (i) the pathogen is present in the field (probability 0.7), (ii) the host plants are susceptible (probability 0.9), and (iii) the humidity is favourable (probability 0.6). (a) Assuming independence, calculate the probability that the disease will occur in a given season. (b) If a fungicide treatment reduces the probability of the pathogen being present by 40 % (i.e., the new probability is 60 % of the original), recalculate the disease occurrence probability after treatment.
