Depends on what is the correct answer!

If a,b,c and d have the same chance (not zero) to be the correct answer, then?

 

[泰迪宝贝]

似乎要复杂些泥，因为不知道正常的答案是哪个呀！

 

[CanMa2011]

If a,b,c and d have the same chance to be the correct answer, then?

Did you see a) and d) are the same?

 

[闲得慌]

Did you see a) and d) are the same?

25%

 

[eyelash2011]

60%

 

[闲得慌]

(50% + 25% + 25%)/3 = 33.3%

千万别读那几个％。

(50% + 25% + 25% +50%)/4 = 37.5%

千万别读那几个％。
