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
That is =
(42.1/100)*37.5
=(421/1000)*(375/10)
=(157875/10000)
=15.7875
=15.8
=16
