1/4= 25/100

25 divided by 100 is 0.25 which is equal to %25

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%
