Ram has 2018 coins.

The \(1^\text{st}\) coin has a \(\frac{1}{2}\) chance of flipping heads, the \(2^\text{nd}\) coin has a \(\frac{1}{3}\) chance of flipping heads, the \(3^\text{rd}\) coin has a \(\frac{1}{5}\) chance of flipping heads, continuing such that the \(k^\text{th}\) coin has a \(\frac{1}{p(k)}\) chance of flipping heads, where \(p(k)\) is the \(k^\text{th}\) prime number.
