It is indeed like lottery for those with no knowledge.
And in that case the chance of succeeding the test is about the same
as the chance of winning the lottery.
In a well designed MC test the chance of succeeding on pure luck is
far less than 1 in a million:
- there is a penalty for wrong answers (so a on average a "monkey"
should end on a zero score)
- the most obvious wrong answers should be in the list
Eg: if the questions is to calculate the voltage over a 10 Ohm
resistor where the current is 5 A the list of answers should include
50 V, 2 V and 0.5 V
