### Convergence of an infinite product $\prod_{k=1}^{\infty }(1-\frac1{2^k})$? [duplicate]

Problem: I want to prove that the infinite product $\prod_{k=1}^{\infty }(1-\frac{1}{2^{k}})$ does not converge to zero. It doesn't matter to find the value to which this product converges, but I am ...
### Is the product $\prod_{k=1}^\infty \frac{2^k-1}{2^k}$ necessarily $0$? [duplicate]
I have the product $\prod_{k=1}^\infty \frac{2^k-1}{2^k}$. I know that every successive partial product will necessarily be smaller than the last, as we are multiplying always by a number smaller than ...
### Evaluate $\prod_{n=1}^\infty \frac{2^n-1}{2^n}$
Is there a closed form expression for this limit? $$\prod_{n=1}^\infty \frac{2^n-1}{2^n}$$ Wolfram Alpha says $0.2887880950866024212788997219292307800889\dots$ and the Inverse Symbol Calculator found ...
