A local animal rescue organization receives an average of 0.55 rescue calls per hour. Use the Poisson distribution to find the probability that during a randomly selected hour, the organization will receive fewer than two calls. A) 0.087 B) 0.894
C) 0.317
D) 0.106

B) 0.894

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.

A local animal rescue organization receives an average of 0.55 rescue calls per hour.

This means that

Probability that during a randomly selected hour, the organization will receive fewer than two calls.

In which

1) is right
