We have
so this is indeed a difference of squares. Factorizing would give
making the answer D.
We can further factor the first term here and write
but that's clearly out of the scope of this question.

Answer:
====================
Total number of outcomes is 16, count of all outcomes.
Number of outcomes with 3 or more tiles is 5:
- HTTT, THTT, TTHT, TTTH, TTTT
The probability is:
- P = favorable outcomes / total outcomes
- P(at least 3 tails) = 5/16 = 0.3125
Correct choice is D.
