Answer:
(C) 0
Explanation:
As always, the first step is to read and understand the question. You are asked to find the smallest number in the set {M₁, M₂, M₃}. Each of these values is defined to be the largest number in the corresponding sets S₁, S₂, S₃.
Set M
The numbers in each set are ordered smallest to largest, so the largest number in each set is the one on the right.
The largest number in S₁ is 8, so M₁ = 8.
The largest number in S₂ is 6, so M₂ = 6.
The largest number in S₃ is 0, so M₃ = 0.
This means the set M is ...
M = {M₁, M₂, M₃} = {8, 6, 0}
The question asks for the smallest number in set M. Clearly, it is 0.
The smallest number in the set is 0.
