WebbThe probability density function (" p.d.f. ") of a continuous random variable X with support S is an integrable function f ( x) satisfying the following: f ( x) is positive everywhere in the support S, that is, f ( x) > 0, for all x in S. The area under the curve f ( x) in the support S is 1, that is: ∫ S f ( x) d x = 1. Webb11 apr. 2024 · Probabilities are most commonly shown as fractions. The probability of getting 'tails' when you toss a coin is a 1 in 2 chance, or 1/2. Probabilities can also be shown as decimals or percentages.
