(a) According to the model, what percent of patients survive 1 year after initial diagnosis? (b) What percent of patients survive 3 years after initial diagnosis? (c) Explain the meaning of the base 0.6 in the context of this problem. (a) According to the model, % of patients survive 1 year after initial diagnosis. (Type an integer or a decimal.) (b) According to the model, % of patients survive 3 years after initial diagnosis. (Type an integer or a decimal.) (c) Explain the meaning of the base 0.6 in the context of this problem. Select the correct choice below and fill in the answer box to complete your choice. O A. As each year passes, % of the previous year's survivors have survived. O B.
