D. theoretical; the probability of flipping heads on a single coin toss is 1/2, and the probability of flipping heads 15 times in a row is (1/2)^15, which simplifies to two-fifths (2/5). This is based on the number of possible outcomes, not on actually performing the experiment.
(1/2)^15 = 1/32,768
NOT 2/5
