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
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.
