Answer:
a) 3.47% probability that there will be exactly 15 arrivals.
b) 58.31% probability that there are no more than 10 arrivals.
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.
If the mean number of arrivals is 10
This means that 
(a) that there will be exactly 15 arrivals?
This is P(X = 15). So


3.47% probability that there will be exactly 15 arrivals.
(b) no more than 10 arrivals?
This is 














58.31% probability that there are no more than 10 arrivals.

Answer:
69.66 Square inches
Step-by-step explanation:
Area of a Square = Length X Length
Length of the Square Pan =18 Inch
- Area of the Square Pan =18 X 18 =324 Square inches
Area of a Circle 
Diameter of the Pizza Pan =18 Inch
Radius =Diameter/2=18/2=9 Inch
- Area of a circular pan

Difference in Area =324-254.34
=69.66 Square inches
A pizza made in the square pan is <u>69.66 Square inches</u> larger than that made in a circular pan.
