Answer:
There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
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.
What is the probability that exactly two such busses arrive within 3 minutes of each other
The mean is one bus each 10 minutes. So for 3 minutes, the mean is 3/10 = 0.3 buses. So we use
This probability is P(X = 2).
There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
