If a certain user has exactly 700 followers and a problem of his can be liked only by his followers with a chance of 0.5. Find the probability that his problem will get at least 3 likes.

The probability can be expressed as $$\dfrac{{b}^{c}-a}{{b}^{c}}$$ where a and b are coprime positive integers with $$b$$ prime.

Give your answer as $$a+b+c$$.
