phi · Answer

on the first question,  if there are 4 choices and you randomly pick one of them, what is the chance you got it correct?  any idea ?

1/4 probability you got one correct... 
Since it is guessed three times you would multiply 1/4 by itself 3 times
$$\frac{ 1 }{ 4 } \times \frac{ 1 }{ 4 } \times \frac{ 1 }{ 4 } = ?$$
