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? 0.250 0.135 0.368 1.00

In a town, the number of electric power failures occurs randomly with an average of one failure every 4 months. Calculate the probability that there will be no failure over the next six months. 0.2231 0.6653 0.1353 0.3679

In a town, the number of electric power failures occurs randomly with an average of one failure every 4 months. What is the variance associated with the number of failures over six consecutive months?

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

61. Se lanza un dado cargado, con forma de dodecaedro ( 12 caras), cuyas caras están numeradas consecutivamente desde el 1 al 12 , en que la probabilidad de caer en un número par es el triple que la de caer en un impar. ¿Cuál es la probabilidad de obtener al menos un 6 ?
