The article “Integrating Risk Assessment and Life Cycle Assessment: A Case Study of Insulation” (Y. Nishioka J. Levy, et al„ Risk Analysis, 2002: 1003-1017) estimates that 5.6% of a certain population has asthma, and that an asthmatic has probability 0.027 of suffering an asthma attack on a given day. A person is chosen at random from this population. What is the probability that this person has an asthma attack on that day?

Answer:

Step 1 of 3:

The event that the randomly chosen from the population is asthmatic is denoted by A.

Since, 5.6% of a certain population have asthma.

Then, P(A) = 0.056.

Let B denotes that an asthmatic have the probability 0.027 of suffering an asthma attack on a given day.

Therefore, P(B) = 0.027.
