Answer:

The disc jockey can simply run a what is called a random experiment. In this experiment, she takes all the songs, and defines the probability of a particular song being played.

Explanation:

More specifically, in her random experiment, the DJ has a specific number of songs in total. Let's assume that she has 9 songs in total: 3 rock songs, 3 country songs, and 3 pop songs. We can assume this because the question says that she has an equal number of songs per genre.

The probability of the first song being a country song is therefore 1/9, because the country song is 1 among 9 songs in total.

The probability of the second song also being a country song is 1/8, because now, there are only 8 songs remaining,

Finally, the probability of the third song also being a country song is 1/7, again, because now, there are only 7 songs remaining.

Now, to find the probability of the first three songs all being country song, we multiply the above probabilities.

1/9 * 1/8 * 1/7 = 1/504 or 0.19%.

As we can see, the probability is extremely low.

por qué la independencia de Centroamérica fue distinta a los procesos de otras partes del continente?
lutik1710 [3]

Answer: Hoy, en 2021, se dice comúnmente que Centroamérica incluye a Guatemala, Belice, El Salvador, Honduras, Nicaragua, Costa Rica y Panamá. Esta definición coincide con las fronteras políticas modernas. Centroamérica comienza geográficamente en México, en el istmo de Tehuantepec, el punto más estrecho de México, y el antiguo país de Yucatán (1841-1848) era parte de Centroamérica. En el otro extremo, antes de su independencia en 1903, Panamá era parte de América del Sur, ya que era un Departamento de Colombia. A veces Belice, una colonia británica hasta 1981, donde se habla inglés en lugar de español, y donde la población es principalmente de origen africano, no se ha considerado parte de América Central (de habla hispana).

Centroamérica, larga y estrecha, no tiene un centro geográfico obvio. Hasta mediados del siglo XX no existían carreteras entre los países, lo que los aislaba entre sí, y los ferrocarriles nunca los han conectado. Durante la época colonial, Guatemala fue el centro administrativo y religioso; religiosamente sigue siéndolo. Sin embargo, los intentos de crear una Unión Política Centroamericana, como la Unión Europea, han fracasado. Los países que se adhirieron a la UE ya contaban con un importante tráfico transfronterizo por tren; incluso hoy (2021), en comparación, hay muy poco y ninguno en tren. Los países centroamericanos no buscan unirse, y mucho menos con su capital en Guatemala.

Los países, además, son más diversos de lo que parecen a primera vista. Algunos (Guatemala) tienen una gran población indígena o nativa americana, otros (Costa Rica) no. Algunos (El Salvador) se concentran en su costa del Pacífico, mientras que en otros (Belice, Honduras) la costa del Caribe o del Atlántico es más importante. Panamá y en menor medida Guatemala y Costa Rica tienen ambas costas jugando un papel importante. Algunos países tienen gobiernos estables (Costa Rica), otros no (Nicaragua, El Salvador). Panamá está fuertemente americanizada, usa el dólar estadounidense como moneda, tiene una gran industria y fuente de ingresos (el canal), y una sofisticación que proviene de los barcos y personas que pasan por el país y anteriormente las instalaciones militares estadounidenses en el antiguo Canal.
