Section 2-1

2-1. Let "a", "b" denote a part above, below the specification
S = {aaa, aab, aba, abb, baa, bab, bba, bbb}
2-2. Let "e" denote a bit in error
Let "o" denote a bit not in error ("o" denotes okay)
⎧eeee, eoee, oeee, ooee, ⎫
⎪eeeo, eoeo, oeeo, ooeo,⎪
⎪ ⎪
S =⎨ ⎬
⎪eeoe, eooe, oeoe, oooe,⎪
⎪⎩eeoo, eooo, oeoo, oooo⎪⎭

2-3. Let "a" denote an acceptable power supply
Let "f" ,"m","c" denote a supply with a functional, minor, or cosmetic error, respectively.
S = {a, f ,m, c}
2-4. S = {0,12
, ,...} = set of nonnegative integers

2-5. If only the number of tracks with errors is of interest, then S = {0,12
, ,...,24}
2-6. A vector with three components can describe the three digits of the ammeter. Each digit can be
0,1,2,...,9. Then S is a sample space of 1000 possible three digit integers, S = {000,001,...,999}
2-7. S is the sample space of 100 possible two digit integers.
2-8. Let an ordered pair of numbers, such as 43 denote the response on the first and second question. Then, S
consists of the 25 ordered pairs {1112
, ,...,55}

2-9. S = {0,1,2,...,} in ppb.
2-10. S = {0,1,2,...,} in milliseconds
2-11. S = {1.0,1.1,1.2, K14.0}
2-12. s = small, m = medium, l = large; S = {s, m, l, ss, sm, sl, ….}
2-13 S = {0,1,2,...,} in milliseconds.
