The number of births in a hospital follows a Poisson distribution with an average number of 1 birth per hour. What is the probability that there will be no birth within the next 2 hours? 1.00 0.135 0.368 0.250

The number of births in a hospital follows a Poisson distribution with an average number of 1 birth per hour. What is the probability that there will be at least one birth within the next 2 hours? \( \frac{0.8647}{0.6321} \) 0.1353

5. En una caja hay 7 tarjetas, de igual forma y tamanoo, con el nombre de los dias de la semana, Se saca una de ellas al azar y se define la variable aleatoria "X: diferencia entre el número de consonantes y vocales de la palabra". Si se saca la tarjeta que dice MIERCOLES, ¿qué valor toma la variable aleatoria para dicha tarjeta? A) -1 B) 0 C) 1 D) \( \frac{5}{4} \)

The number of births in a hospital follows a Poisson distribution with an average number of 1 birth per hour, What is the probability that there will be at least one birth within the next 2 hours? 0.8647 0.6321 0.1353 0.2707

10. Una moneda cuyas caras están marcadas con los números 2 y 3 , respectivamente, es tirada 5 veces. ¿Cuál es la probabilidad de obtener un total de \( 12 ? \) \( \begin{array}{lll}\text { A) } \frac{25}{16} & \text { B) } \frac{5}{16} & \text { C) } \frac{5}{4} \\ \text { D) } \frac{6}{25} & \text { E) } \frac{5}{6}\end{array} \)

The number of births in a hospital follows a Poisson distribution with an average number of 1 birth per hour. What is the standard deviation associated with the number of births within a whole day (i.e. over 24 hours)?
