Starting from a geometrical reading of the error estimate due to the Bramble\u2013Hilbert lemma, we derive two probability distributions that estimate the relative accuracy, considered as a random variable, between two Lagrange finite elements <jats:inline-formula id=\"j_cmam-2018-0270_ineq_9999\">\n                     <jats:alternatives>\n                        <m:math xmlns:m=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                           <m:msub>\n                              <m:mi>P<\/m:mi>\n                              <m:mi>k<\/m:mi>\n                           <\/m:msub>\n                        <\/m:math>\n                        <jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/j_cmam-2018-0270_eq_0085.png\"\/>\n                        <jats:tex-math>{P_{k}}<\/jats:tex-math>\n                     <\/jats:alternatives>\n                  <\/jats:inline-formula> and <jats:inline-formula id=\"j_cmam-2018-0270_ineq_9998\">\n                     <jats:alternatives>\n                        <m:math xmlns:m=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                           <m:msub>\n                              <m:mi>P<\/m:mi>\n                              <m:mi>m<\/m:mi>\n                           <\/m:msub>\n                        <\/m:math>\n                        <jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/j_cmam-2018-0270_eq_0086.png\"\/>\n                        <jats:tex-math>{P_{m}}<\/jats:tex-math>\n                     <\/jats:alternatives>\n                  <\/jats:inline-formula> (<jats:inline-formula id=\"j_cmam-2018-0270_ineq_9997\">\n                     <jats:alternatives>\n                        <m:math xmlns:m=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                           <m:mrow>\n                              <m:mi>k<\/m:mi>\n                              <m:mo>&lt;<\/m:mo>\n                              <m:mi>m<\/m:mi>\n                           <\/m:mrow>\n                        <\/m:math>\n                        <jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/j_cmam-2018-0270_eq_0143.png\"\/>\n                        <jats:tex-math>{k&lt;m}<\/jats:tex-math>\n                     <\/jats:alternatives>\n                  <\/jats:inline-formula>).
