Answer:

The probability that a selected person has an asthma attack on that day is 0.001458

Step-by-step explanation:

Let A = A person has asthma

B =A person suffers from an asthma attack in a day

P(A) = Probability that a person has asthma= 5.4% = 0.054

P(B/A)= Probability that a person suffers from asthma = 0.027

Let P(A n B) = The probability that a selected person has an asthma attack on that day

P(A n B) = P(A) * P(B/A)

P(A n B) = 0.054 * 0.027

P(A n B) = 0.001458
