Question 498943: Hello:
I am working on a practice test and it would be dishonest of me to ask you the same question. However, I am having a horrible time discerning how to write a recursive pattern. I know how to find the pattern, no problem, see that right away, but when it comes to figuring out the pattern I get a mental block.
Is there a resource you can recommend to me to sort this out? I would be happy to study it as I want to understand this.
Tina

Question 465514: The Fundamental Counting Principle states that the number of ways in which a series of successive things can occur is found by multiplying the number of ways in which each thing can occur. That is, if first event E1 can occur in M1 different ways and after E1 has occurred, if event E2 can occur M2 different ways, then total number of ways that two events can occur is M1*M2
1.Based on this principle, how many different Social Security numbers are possible?
2.Can you find out how many telephone numbers are possible within any area code?
3.Try following problem using Fundamental Counting Principle.
A typical alarm code is unarmed with the correct sequence of three numbers between 0 and 49 inclusive. If a burglar takes one second to try one sequence of
alarm code, how long (in hours) will take for a burglar to try all possible sequences? Is this alarm code systems deterrent enough to keep burglars away?
