Question 1
In a factory, 80% of machinery is working. If a machine is selected and found to be faulty (20% failure rate), what is the conditional probability that another machine from the same batch is also faulty?
💡 Hint: Analyze the relationship and use previous probabilities.
Question 2
If a test for a rare disease is 92% accurate and the prevalence in the population is 0.5%, what is the probability someone who tests positive actually has the disease?
