Answer:
The symbolic way to represent the probability of a true positive is:
P(I∩D)
Step-by-step explanation:
The representation is given as follows:
I for infected; U, uninfected; D, infection detected; and N, no infection detected.
We are asked to find which expression represents the probability of a true positive.
i.e we are asked to find the probability that a person who is infected is also detected.
Let P denote the probability of an event.
Hence, the expression is:
P(I∩D)
Answer:
f(x) = 3x^2 + 11x – 12.

Answer:
The probability that no one in a family of five will be hospitalized in a year is 0,2373
Step-by-step explanation:
Let p denote the probability of being hospitalized during a year,
Then p=0.25
And p' the probability of not being hospitalized during a year is 1-p
Thus p' = 1-p = 1-0.25 = 0.75
The probability that no one in a family of five will be hospitalized in a year is equal to . That is
= ≈ 0,2373
