... I want to calculate P(Y < 1.5), but I recognize that it would be simpler if we calculated instead P(Y > 1.5) the complement of what I really want. Thus P(Y < 1.5) = 1 – P(Y > 1.5) ...

... 1) In the relative frequency formula, the probabilities are determined by conducting an experiment, counting the number of occurrences of the event, and creating the ratio of number of occurrences to number of times the experiment was conducted. In the classical approach, a sample space of all of th ...

... example, if a game results in one H and thee T, Brian loses $2]. Brian’s possible outcomes are {-4, -2, 0, 2, 4}. Assign probabilities to these outcomes by playing the game 20 times [or simulating 20 times] and using the proportions of the outcomes to estimate the probabilities. Combine your trials ...
