Given a input string and 'n' random subsequences of that string , what is the probability of realizing original string using these subsequences correctly?

Example :

Given string = "MISSISSIPPI"

Subsequences:

1) "MISS"

2) "III"

3) "MIP"

4) "SIS"

5) "IS"

6 ) "SP"

7) "MP"

How many subsequences will be required for optimal probability?

Is there any specific structure for subsequences for optimal probability?

Hi MonD;

Some questions about your question. With your sub sequences how would you ever get SIP?

What do you mean by optimal probability?

**In mathematics, you don't understand things. You just get used to them.**

**I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.**
