The document you uploaded is an assignment for the course "MHZ3576: Statistics for Industrial Studies," focusing on probability and probability distribution. Below are the problems from the assignment:

1. **Machine Malfunctions** (related to operator error and probability distributions):
   - a) Identify the type of probability distribution.
   - b) Calculate the expected number of reports to be reviewed before finding an operator error.
   - c) Determine the probability of needing to review at least three reports.

2. **Car Spoiler Inspection** (involves quality control and defect probabilities):
   - a) Probability that the shipment will be returned if 20% or more parts are defective.
   - b) Probability of finding at most 5 defective parts.
   - c) Average number of defects in a shipment.

3. **Gerber Cutting Machine Faults** (fault occurrence rate):
   - a) Probability of no faults in a minute.
   - b) Probability of 2 to 5 faults in a minute.
   - c) Expected number of faults in an hour.

4. **T-shirt Length** (normally distributed lengths):
   - a) Proportion of t-shirts between 580mm and 640mm.
   - b) Adjust the mean length to ensure 95.15% of t-shirts are less than or equal to 690mm.

If you'd like help with any specific questions or explanations, let me know!

Do you have any specific questions or need a detailed solution? Here are five related questions:

1. What is a geometric distribution, and where is it used?
2. How do you calculate the binomial probability of defects?
3. What is the Poisson distribution, and how is it applied to fault rates?
4. How do you find probabilities in a normal distribution?
5. How do changes in mean and standard deviation affect a normal distribution?

**Tip**: Always identify the type of probability distribution before solving the problem—it simplifies the solution process.
