Typo on #8 from exercises at end of Ch. 3

[Rick Grush]

There is a typo on problem #8 at the end of Ch. 3. In the text premise 2 is

2. ~O v E

But it should be a conjunction:

2. ~O & E

Note I used an ampersand above, &, rather than the correct symbol, the dot, to make sure everyone could read it in their email correctly.
