Q:

HELLLPPPPPPP .... The probabilities of a test are represented by I for infected; U, uninfected; D, infection detected; and N, no infection detected. What is the symbolic way to represent the probability of a true positive?A. `"P"("I" nnn "D")`B. `("P"("I" nnn "D"))/("P"("D"))`C. `("P"("U" nnn "N"))/("P"("N"))`D. `"P"("I" uuu "D")`

Accepted Solution

A:
Answer:P(Iβ‹‚D)Step-by-step explanation:The symbolic way to represent the probability of a true positive is P(Iβ‹‚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.
