QUESTION:
Consider the bar code in Example 2-12. Suppose that all 40 codes are equally likely (none is held back as a delimiter). Determine the probability for each of the following:
(a) The second bar is wide given that the first bar is wide.
(b) The third bar is wide given that the first two bars are not wide.
(c) The i rst bar is wide given that the last bar is wide.
ANSWER:
Solution:
Step 1 of 4:
A bar code system consists of tight and wide bars separated by either wide or limit space.
Each character contains nine elements (five bars and four spaces). The code for a character starts and ends with a bar and space in each character.
