In a city with 40000 people, each person has a 0.00020 probability of committing a crime each hour. What is the probability that there are exactly 3 crimes during the next hour

2.86% probability that there are exactly 3 crimes during the next hour

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which

x is the number of sucesses

e = 2.71828 is the Euler number

is the mean in the given time interval.

In a city with 40000 people, each person has a 0.00020 probability of committing a crime each hour.

So

What is the probability that there are exactly 3 crimes during the next hour

This is P(X = 3).

2.86% probability that there are exactly 3 crimes during the next hour

tip $2.90

total $17.40

inverse property is the answer
