We know that Among 9 electrical components, exactly one is known not to function properly. If 3 components are randomly selected.
We calculate the probability that all selected components function properly.
We calculate the number of possible combinations:

We calculate the number of favorable combinations:
Therefore the probability is:

See, pls, offered explanation:
1) the both equations are linear function, it means system made up of the both equation has the only solution.
2) if to prove this:

Answer: one solution.
Answer:
The second works better because:
577-479= 577-(477+2)= 577-477-2=100-2=98
