Using the Fundamental Counting Theorem, it is found that there is a probability of getting the correct Social Security number of the person who was given the receipt.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
In this problem, there are 5 digits, each with 10 possible options, hence the number of options is given by:
Only one option is correct, hence the probability is given by:

Answer:
Step-by-step explanation:
Let the boy's present age be x.
Let his dad's present name be y.
Last year, his dad was 8 times as old as him. Subtract one year from each their ages and multiply the son's age by 8:
(y - 1) = 8(x - 1) ______ (1)
Now, his dad's age is the square of his age:
y = _________(2)
From (1):
y = 8x - 8 + 1
y = 8x -7
Put this in (2):
This problem has been represented in the form of a quadratic equation.
Answer:
I do not know sorry for taking your points
The answer is —2
Each number is multiplied by —2 to get the following number in the pattern
Hope this helps and good luck you can do thissss :)
