(b) If the stoplight is either green or yellow, I can legally proceed through the intersection. The stoplight is red, so I cannot legally proceed.

Explanation / Answer
1
a)Inductive
The statement says that "that every day that the sun does not shine, it rains" and Today is cloudy, so it must be raining. The conlcusion doesn't logically follows. It may be just cloudy and not raining right now.
b)Inductive
The sun has always risen in the morning is just an observation according to the given statement.We can't guarantee the given conclusion based only on the given statement. Hence, the conlcusion doen't follows logically.
c)Deductive
Statement says tomorrow will come. The conclusion also says tomorrow will come. No confusion.
2.
a) Not valid. Even if I pass my driving test i might not have license because of under age or other issue.
b) Not valid. The statement only says that "If the stoplight is either green or yellow, I can legally proceed through the intersection." It doesn't say anything about Red signal. Be careful, don't confuse truth with validity.
c)Not Valid."The eggs are not dry"can be due to various reasons. What if somebody poured water after cooking too long.
