The following lists the joint probabilities associated with smoking and lung disease among 60-to-65 year-old men. Has Lung Disea
Anna71 [15]

Answer:

4.11% probability that he has lung disease given that he does not smoke

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Does not smoke

Event B: Lung disease

Lung Disease/Nonsmoker 0.03

This means that P(A \cap B) = 0.03

Lung Disease/Nonsmoker 0.03

No Lung Disease/Nonsmoker 0.7

This means that P(A) = 0.03 + 0.7 = 0.73

What is the probability of the following event: He has lung disease given that he does not smoke?

P(B|A) = \frac{0.03}{0.73} = 0.0411

4.11% probability that he has lung disease given that he does not smoke

MAX POINTS!!! Write and solve a system of equations. Be sure to label the variables. The difference of two numbers is two. Two t
Cerrena [4.2K]

Answer:

  • 5 and 3

Step-by-step explanation:

Let the numbers be x and y.

<u>The equations are:</u>

  • x - y = 2
  • 2x + y = 13

<u>Add up the equations to eliminate y and solve for x:</u>

  • x - y + 2x + y = 2 + 13
  • 3x = 15
  • x = 15/3
  • x = 5

<u>Now find the value of y:</u>

  • y = x - 2
  • y = 5 - 2
  • y = 3
