We focus on $N$ binary random variables correlated in a {\it scale-invariant} way. The correlations are introduced by imposing the Leibnitz rule on a probability set based on the so-called $q$-product with $q \le 1$. We show that, in the large $N$ limit (and after appropriate centering, rescaling, and symmetrisation), the emerging distributions are $q_e$-Gaussians, i.e., $p(x) \propto [1-(1-q_e) β(N) x^2]^{1/(1-q_e)}$, with $q_e=2-\frac{1}{q}$, and with coefficients $β(N)$ approaching finite values $β(\infty)$. The particular case $q=q_e=1$ recovers the celebrated de Moivre-Laplace theorem.Minor improvements and corrections have been introduced in the new version. 7 pages including 4 figuresStatistical Mechanicstext
