    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 \[\frac{ 1 }{ 4 } \times \frac{ 1 }{ 4 } \times \frac{ 1 }{ 4 } = ?\]
