Math Problem Statement
Solution
The image appears to contain a probability-related problem. Let me extract and solve it for you.
The text seems to describe a scenario with two probabilities:
- A machine operates successfully with a probability of .
- If it fails, it will fail again with a probability of .
Two questions are asked:
- What is the probability of a failure?
- Given that it has occurred, what is the probability that a failure is recorded on the second run?
Let me calculate the answers for these questions:
-
The probability of a failure (P(failure)) is simply the complement of the success probability:
-
Given that a failure has occurred on the first run, the probability of failure on the second run is given as . Thus, the second part involves conditional probability.
I'll calculate these now.1. The probability of a failure is or 8%.
- Given that a failure has occurred, the probability that a failure is recorded on the second run is or 65%.
Would you like further details or explanations on these concepts?
Here are five related questions to expand your understanding:
- How do you calculate the probability of multiple independent events?
- What is conditional probability and how does it apply to dependent events?
- How would the result change if the machine had a different success rate?
- How do you calculate the probability of at least one failure in two trials?
- Can you calculate the expected number of failures over several trials?
Tip: Understanding the complement rule is key to solving many probability problems. It states that the probability of an event not occurring is 1 minus the probability that it does occur.
