Ej21. The proportion of patients who are cured of a disease through a treatment is equal to 0.8. If 20 patients of this disease are undergoing the treatment, what probability will there be that 18 patients will be cured?.


We conduct a data compilation given by problem statement:

· X ≡ 'Number of patients who are cured of a disease through a treatment'.
· The random variable X follows a Binomial distribution: X ~ B(20, 0.8).

We have to get the following probability:

P(X = 18) = ₂₀C₁₈·0.8¹⁸·(1-0.8)^20-18 ≈ 0.136909
Finally, the probability of being cured 18 patients with this treatment is 0.136909.
