Answer:

A) P ( I ∩ D )

Step-by-step explanation:

To find a <em>true positive</em>, we need to find the chance of two events happening: <em>an infection is detected and the person has said infection</em>. That means that it is when <em>both I and D are true</em>.

When in a set, two events happen simultaneously, it is shown with a ∩ (intersection) symbol.

That means that a true positive is shown as P (I ∩ D)

Answer:

P(I⋂D)

Step-by-step explanation:

The symbolic way to represent the probability of a true positive is P(I⋂D).

We know that I stands for Infected, U stands for Uninfected, D for Infection detected, N for infection no detected.

Then, a true positive will be given by the intersection of Infected and Infection Detected.
