WebbThe results of a sample space are called equally likely if all of them have the same probability of occurring. For example, if you throw a die, then the probability of getting 1 is 1/6. Similarly, the probability of getting all the … WebbFor example, the probability of getting two "tails" in a row would be: P (T and T) = 1 2 ... This formula says that we can multiply the probabilities of two events, but we need to take the first event into account when considering the probability of the second event.
WebbIn probability theory, a probability density function (PDF), or density of an absolutely continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be equal to … Webb11 jan. 2024 · After dividing the result by the total number of students she will find the desired probability.
