The definition of probability of an event is the number of outcomes where the event occurs divided by the total number of possible outcomes. In this case, there are 2 possible outcomes (heads or tails) and the coin was flipped 1,000,000 times. Therefore, the probability of getting heads is 600,000/1,000,000 or 0.6.
