8. According to a study conducted by the Department of Pediatrics, children who are injured two or more times tend to sustain these injuries during a relatively limited time. If the average number of injuries per year for children is λ = 2, what is the probability that a child will sustain exactly three injuries during the year?

Transcribed Image Text:**Problem Statement: Understanding the Probability of Injuries**
According to a study conducted by the Department of Pediatrics, children who are injured two or more times tend to sustain these injuries during a relatively limited time. If the average number of injuries per year for children is represented by λ = 2, what is the probability that a child will sustain exactly three injuries during the year?
**Guidance:**
This problem involves calculating the probability of a specific number of occurrences (in this case, injuries) given a known average rate, which suggests the use of the Poisson distribution. The Poisson distribution is useful for modeling the number of times an event happens in a fixed interval of time or space. Here, you can apply the Poisson probability formula to determine the likelihood of exactly three injuries occurring.
Expert Solution
