What is the probability of rolling a number greater than 2 with a 6 sided die, three times in a row?

A number greater than 2 is: 3, 4, 5, 6
Roll 1: 4 numbers out of 6 numbers total = 4/6 = 2/3
Roll 2: (same as roll 1)
Roll 3: (same as roll 1)

Roll 1 AND Roll 2 AND Roll 3
 2/3      x      2/3       x     2/3    = 2³/3³ = 8/27
