The probability of rolling a die and getting an even number is 1/2. If you roll the die twice, the probability of getting a even number both times is (1/2)(1/2) or (1/2)^2. Write an expression to represent the probability of rolling the die (d) times and getting an even number every time. Write the expression to the power of 2.

if getting an even number twice is (1/2)^2
and getting an even number three times is (1/2)^3
then getting an even number d times is (1/2)^d
or
2^d
