Ashley starts with 45 comics.
So in the first box:
x = 0, y = 45
-------------------------------------------------------------------------------------------------------
Each month, she adds 5 comic books to her collection
x (+1), y (+5) (for each month).
First month.
x = 0
y = 45
Second month
x = 1
y = 45 (+5) = 50
Third month
x = 2
y = 50 (+5) = 55
etc.
-------------------------------------------------------------------------------------------------------
B) is your best choice, as for every month add (+1), the comic books increase by 5 respectively.

hope this helps
B. congruent, im pretty sure
Another way is the formula:

Hope this helps!
Answer:

Step-by-step explanation:
Part (a) the probability that two people have a birthday on the 9th of any month.
Neglecting leap year, there are 365 days in a year.
There are 12 possible 9th in months that make a year calendar.
If two people have birthday on 9th; P(1st person) and P(2nd person).

Part (b) the probability that two people have a birthday on the same day of the same month
P(2 people selected have birthday on the same day of same month) + P(2 people selected not having birthday on same day of same month) = 1
P(2 people selected not having birthday on same day of same month):

P(2 people selected have birthday on the same day of same month)
