A Geneticist Developed a New Type of Pest-Resistant Walnuts

Multiple Choice

A geneticist developed a new type of pest-resistant walnuts. These walnuts produce 75% of pest-resistant walnut trees and 25% of susceptible (not resistant) trees when two resistant trees are crossed. If a grower crosses two such trees, the outcome is random and a probability model is given by:

A) resistant and susceptible.
B) probabilities p = 0.70 and p = 0.3.
C) P(resistant) = 0.75 and P(susceptible) = 0.25.
D) P(resistant) = 0.7.
