    Forming Sums As discussed above, for three dice the possible sums include every number from three to 18 The probabilities can be calculated by using counting strategies and recognizing that we are looking for ways to partition a number into exactly three whole numbers For example, the only way to obtain a sum of three is 3 = 1 + 1 + 1Structural Investigations of Solidification and Heat Treatments Influence on High Alloyed Cast Irons Grades with NbVTi additions Jacqueline LecomteBeckers 1, a and Jérôme Tchoufang Tchuindjang 1,b 1University of Liege, Aerospace & Mechanics Dpt, Metallurgy & Materials Science unit – IMGC, BâtStructural Investigations of Solidification and Heatrolling the sequence 1,1,2,1,6 Rolling five 4's An outcome is a specific result of an experiment So the outcomes of this experiment are all the possible sequences of five die rolls So in this case, a particular sequence such as 1,1,2,1,6 is an outcome So is rolling five 4's, because this is a specific outcome (4,4,4,4,4)Probability Terminology and Notation Flashcards | Quizlet
