![]() As more trials are added, students will see how the outcome probabilities can be predicted using Pascal’s triangle. In the Balancing Chemical Equations Gizmo, look at the floating molecules below the initial reaction: H2+ O2 H2O. The Gizmo illustrates the possible outcomes of multiple trials with a tree diagram. products This process is summarized by a chemical equation. In the Gizmo, students simulate the results of successive trials in which the two outcomes are success and failure, similar to a coin toss experiment. Students can learn about the basics of probability theory in the Binomial Probabilities Gizmo. ![]() Pascal’s most significant contribution to mathematics was as the co-inventor of the field of probability, in collaboration with Pierre de Fermat. At 19, he invented a mechanical calculator to help his father with this tax work. Pascal was only 16 when he discovered his first mathematical theorem. During his short life (he died at the age of 39), Pascal made major contributions to mathematics, science, philosophy, and religion.įrom a young age, Pascal took an interest in mathematics. Introduction: It is important to distinguish chemical changes, in which new substances are formed, from physical changes, which do not create new substances.
