The strategy or equation which do not solve this problem is letter A and B.
The letter A goes m=(30+45+35)/6, the question asked how many minutes Ella will babysit in six weeks. In a week Ella babysits for 110 minutes, instead of dividing it by 6 weeks (which is shown in the equation of letter A), you have to multiply by 6 weeks. It should go like this, m= (30+45+35) x 6.

Answer:
There is a 99.44% probability that the squad will have at most 2 calls in an 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 this problem, we have that:
2.83 rescues every eight hours.
What is the probability that the squad will have at most 2 calls in an hour?
This is
We have 2.83 rescues every 8 hours. So for an hour, we have
So
So
There is a 99.44% probability that the squad will have at most 2 calls in an hour.
