Question

Parts a-e

**Probability**

The datafile linked below summarizes the number of traffic accidents in the USA in 2020, split across the vehicle chassis type. Take the probability of any given crash involving a particular chassis/body type as the relative frequency (percentage) of crashes that did in this dataset.

The probability of an individual being male based on this dataset is 0.4948 and the probability of being female is 0.5052.

**Bar Graph: Number of Vehicles in Thousands**

- **Passenger Car**: 4,748
- **Light Truck**: 3,801
- **Large Truck**: 439
- **Motorcycle**: 106
- **Bus**: 31
- **Other or Unknown**: 19

The horizontal axis represents the number of vehicles in thousands, ranging from 0 to 5,500.

**Questions:**

(a) What is the probability that a randomly selected accident involved a bus?

(b) What’s the probability two randomly selected accidents involve at least 1 light truck?

(c) Given a crash did not involve a passenger car, what’s the probability it involved a light truck?

(d) Assuming the accidents are selected independently, what’s the probability a sample of 20 randomly selected accidents contains at least 5 that involve passenger cars?

(e) What’s the expected number of accidents in a randomly, independently selected sample of 20 that involve buses?
