  skos:definition """En théorie des probabilités et en statistique, la <b>loi géométrique</b> désigne, selon la convention choisie, l'une des deux lois de probabilité suivantes :  <ul><li>la loi du nombre <span class="texhtml mvar" style="font-style:italic;">X</span> d'épreuves de Bernoulli indépendantes de probabilité de succès <span class="texhtml"><i>p</i> ∈ ]0,1[</span> (ou <span class="texhtml"><i>q</i> = 1 – <i>p</i></span> d'échec) nécessaire pour obtenir le premier succès. <span class="texhtml mvar" style="font-style:italic;">X</span> est la variable aléatoire donnant le rang du premier succès.
