Which one of the following languages over the alphabet {0,1} is described by the regular expression: (0+1)*0(0+1)*0(0+1)*?
  • a)
    The set of all strings containing the substring 00.
  • b)
    The set of all strings containing at most two 0’s.
  • c)
    The set of all strings containing at least two 0’s.
  • d)
    The set of all strings that begin and end with either 0 or 1.
Correct answer is option 'C'. Can you explain this answer?

Given regular expression: (0 1)*0(0 1)*0(0 1)*

To understand the language described by the regular expression, let us break it down into its components:

(0 1)* - Any number of occurrences of 0 or 1 (including none)
0 - A single occurrence of 0
(0 1)* - Any number of occurrences of 0 or 1 (including none)
0 - A single occurrence of 0
(0 1)* - Any number of occurrences of 0 or 1 (including none)

This regular expression matches any string that contains at least two occurrences of the digit 0. Therefore, the language described by this regular expression is the set of all strings containing at least two 0s, which is option C.

To further illustrate this, we can consider a few examples of strings that would be matched by this regular expression:

- 0010
- 110100
- 0010010
- 001111010

All of these strings contain at least two occurrences of the digit 0, and thus would be included in the language described by the regular expression.
