QUESTION 11 75% of the people in the region have the virus (V). Of those who have the virus, 20% are over 50 years old (O). Of those who don't have the virus, 10% are over 50 years old. Let O stand for "Over 50 years old." What is the probability that a person has the virus and is over 50 years old? O P(O | V) = 0.75 O P(V | 0) = 0.75 * 0.10 O P(V n 0) = 0.20 * 0.75 O P(V) = 0.20
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
