A six-sided number cube numbered 1 through 6 is rolled 270 times. The number 3 comes up 44 times. What is the theoretical probability of rolling a 3? What is the experimental probability of rolling a 3?​

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
