The answer explains permutations in the context of flipping a coin four times to determine the probabilities of getting different outcomes.
Permutations involve arranging elements in a specific order. In this case, the question is looking at the probabilities of different outcomes when flipping a coin four times.
The probabilities provided represent the different combinations of getting heads (H) and tails (T) in the four coin flips. For instance, P{X=1} means the probability of getting 1 head and 3 tails.
Understanding permutations is crucial for calculating probabilities in situations where the order matters, such as arranging people in a line or dealing cards in a specific sequence.
