Question 7 A new drug has been introduced to bring hypertension under control-that is, to reduce high blood pressure to normotensive levels. For any clinical practice among 4 patients, let X be the number of patients of four who are brought under control. There is a table that gives the values of X and the corresponding probabilities, according to a previous study with the drug. However, part of the table is damaged. 0 1 2 3 ?
