Answer:
0.000298 = 0.0298% probability that the system will collapse
Step-by-step explanation:
Number of possible ways the system can fail:
2 lines from a set of 3 fail, or all three fail.
Two from a set of 3:
Can be A and B, A and C, or B and C. Three possible outcomes then.
The probability of each is:
0.01*0.01*0.99
Two failling, each with 0.01 probability, and 1 working, with 0.99 probability.
All three:
Each with 0.01 probability.
a) What is the probability that the system will collapse
Both cases, so
0.000298 = 0.0298% probability that the system will collapse
Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so 
If so, then the contrapositive of that would be
which is the final answer.
The tilde sign
means "not" so writing 
means "not q" which is the complete opposite of q.
If so, then the contrapositive of that would be
The tilde sign
