Challenge
Bayes Theorem is crucial for a data scientist, so try to consolidate knowledge!
Task
Imagine that we decided to conduct medical research. You gathered data about two groups of people: 750
people with heart problems and 800
people with chronic stomachache. You know that 7%
of interviewed from the first group have diabetes; meanwhile, 12%
of respondents from the second group have diabetes too. Calculate the probability that a randomly selected person with diabetes has a chronic stomachache.
- Calculate the probability that a randomly selected person has a heart problem.
- Calculate the probability that the randomly selected person has a stomachache.
- Calculate the probability that you randomly select a person that has diabetes.
- Calculate the probability that a randomly selected person with diabetes has a chronic stomachache (already done).
