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.

Hello there!
The expression:48x+ 56xy
We know we can't add them together since 56 is being multiplied by y. We aren't going to combine 48x and 56xy. They will remain separate terms.
We know that "C" and "D" are not the answers.
However, we can check the following expressions to see if they match the given expression.
8x(6+7y)= 8x*6= 48x 8x*7y= 56xy <=== "A" is correct
"A" is the correct answer.
I hope this helps!
