WebLa toma de decisiones está en la esencia de los negocios. Gerenciar es tomar decisiones, muchas veces bajo presión, con información desordenada y en un contexto de incertidumbre. Un aspecto básico es entender y analizar la información, organizar los datos de forma de facilitar su posterior uso y la toma de decisiones. WebThe probability distribution of a continuous random variable, known as probability distribution functions, are the functions that take on continuous values. The probability of observing any single value is equal to $0$ since the number of values which may be assumed by the random variable is infinite.
