On average, the shoppers across McMaster Univerisity have 2 customers per hour and assuming that for the next hour the number of customers denoted by X, follows a Poisson Distribution. Find the probability that at least two customers are there for the next hour.

0.5940 = 59.40% probability that at least two customers are there for 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 interval.

On average, the shoppers across McMaster Univerisity have 2 customers per hour

This means that

Find the probability that at least two customers are there for the next hour.

This is:

In which

. So

0.5940 = 59.40% probability that at least two customers are there for the next hour.
