Un curso esta formado por 12 mujeres y 15 hombres ¿cual es la probabilidad de que las personas en el cargo de presidente y visep
riadik2000 [5.3K]

Answer:

P = (12/27)*(11/26) = 0.188

Step-by-step explanation:

Si todos tienen la misma probabilidad de estar en cargo de presidente y vicepresidente, entonces:

La probabilidad de que una mujer sea presidente, es igual al cociente entre el número de mujeres y el número total de personas:

p = 12/27

Ahora queremos calcular lo mismo para vicepresidente, y el cálculo es exactamente igual, con la diferencia de que en esta situación, ya hay una mujer en el cargo de presidente, entonces hay 11 mujeres que pueden ser vicepresidente, y un total de: (11 + 15 = 26 personas)

Entonces ahora la probabilidad es:

q = 11/26

La probabilidad conjunta (es decir, la probabilidad de que ambos eventos pasen) es igual al producto de las probabilidades individuales.

P = (12/27)*(11/26) = 0.188

My name is Ann [436]

x = 2  \\ y = 7

is the answer to:

y = 11 - 2x \\ 4x - 3y =  - 13

_________________________________________

x = 5 \\ y = 2

is the answer to:

2x + y = 12 \\ x = 9 - 2y

_________________________________________

x = 3 \\ y = 5

is the answer to:

2x + y = 11 \\ x - 2y =  - 7

_________________________________________

x = 7 \\ y = 3

is the answer to:

x + 3y = 16 \\ 2x - y = 11
