Helll 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")`

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.

A) P ( I ∩ D )

Step-by-step explanation:

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

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)

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

its totaly b
