WebbThere are six faces on a die and each face has the same probability (1 ∕ 6) of coming up whenever we roll the die. This means that if we roll a die 60 times we can expect each of the six faces to come up an equal amount of times, which would be 60 ∕ 6 = 10. Thereby we can say that as Dave is to roll a die 60 times, he should expect 10 of ... Webb1.1 Expectancy-Value Theory. As formulated by Eccles and colleagues, expectancy-value theory holds that achievement-related choices—such as deciding to major in engineering with the goal of becoming a civil engineer—are governed by a variety of factors (Eccles, 1994; Eccles (Parsons) et al., 1983; Meece, Eccles-Parson, et al., 1982 ).
