Acertain system can experience three different types of defects. let ai (i = 1,2,3) denote the event that the system
has a defect of type i. suppose that
p(41) = 0.31, p(a2) = 0.34, p(a3) = 0.4,
p(a, u a2) = 0.58, p(a1 u a3) = 0.62,
p(a2 u az) = 0.65, p(a, na az) = 0.01
(a) find the probability that the system has exactly 2 of the 3 types of defects.
(b) find the probability that the system has a type 1 defect given that it does not have a type 2 or type 3 defect.

with part b plzzz

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes. 

step-by-step explanation:

slope intercept form is y = mx + b

the answer to 3p+12m+8=23pm
