The probability that she will draw the 1 the first time = 1/4 .

The probability that she will draw the 1 the second time = 1/4 .

The probability that she will draw the 1 the third time = 1/4 .

The probability of all three events happening is

               (1/4) · (1/4) · (1/4)  =   (1/4³)  =  1/64

         or   (0.25)³  =  0.015625  =  1.5625%
