Lifetime of certain device is ~distributed random t-lop variable 1/lambda. =10. the system consists of6 devices of such type and is in working condition if all of its components are in working condition. you buy for the system devices that were already used for 4 years find the probability that system that it will not fail in the next 5 years?

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
