WebbThe probability of any one of them is 1 6 Probability In general: Example: the chances of rolling a "4" with a die Number of ways it can happen: 1 (there is only 1 face with a "4" on it) Total number of outcomes: 6 (there are 6 faces altogether) So the probability = 1 6 Example: there are 5 marbles in a bag: 4 are blue, and 1 is red.

WebbFor example, f ( 0.9) = 3 ( 0.9) 2 = 2.43, which is clearly not a probability! In the continuous case, f ( x) is instead the height of the curve at X = x, so that the total area under the curve is 1. In the continuous case, it is areas under the curve that define the probabilities. river ridge apartments burnsville mnWebbProbability examples and solutions - Probabilities: Problems with Solutions Problem 1.
