the tests are correct. How do you expect anyone to trust your judgment here when you don't provide the input to actually prove your point? ;)

('Unlocked', 0, ['Locked', 'Unlocked', 'Unlocked', 'Unlocked', 'Locked', 'Unlocked', 'Locked', 'Locked', 'Locked', 'Unlocked']) should equal ('Unlocked', 1, ['Locked', 'Unlocked', 'Unlocked', 'Unlocked', 'Locked', 'Unlocked', 'Locked', 'Locked', 'Locked', 'Unlocked'])
How should output value equal 1.It should be zero.There are two test cases, I think like this which are wrong.

• "It would be better" sounds like a suggestion, not an issue.
• The description you are seeing is for JavasScript, which doesn't require quote. The real issue would be rather that there is no code block specific for Python. Though, I think it's understandable and there is no mistake possible, one must respect the features of his language.

It would be better to put the keys in the dictionary given in the description box in string quotes

The final result should be a tuple of floats.

Really great one, learned stuff about probability ... liked it though my code is, like alway, inefficent

Strings 'n', 'a', 'q' do not represent decimal numbers. If you have a variable named n and you want to convert it to a decimal number then write Decimal(n).

b=d.Decimal('n')*d.Decimal('a')*d.Decimal('q')
decimal.InvalidOperation: [<class 'decimal.ConversionSyntax'>]
What is the error here?

define "here"? (language? version?)
