Si elegimos un día de la semana al azar, ¿qué probabilidad hay de que sea fin de semana (ya sabemos que hay dos días…)?

irga5000 [103]

Answer:

La probabilidad que hay de que sea fin de semana es $\frac{2}{7}$

Step-by-step explanation:

La Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso. En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles. Entonces, la probabilidad de un suceso cualquiera A se define como el cociente entre el número de casos favorables (número de casos en los que puede ocurrir o no el suceso A) y el número total de casos posibles. Esta se denomina Ley de Laplace.

$P(A)=\frac{numero de casos favorables}{numero de casos posibles}$

En este caso:

número de casos favorables: 2 (cantidad de días del fin de semana)
número de casos posibles: 7 (cantidad de días totales en la semana)

Reemplazando:

P(A)= $\frac{2}{7}$

La probabilidad que hay de que sea fin de semana es $\frac{2}{7}$

20y = 120*1
20y/ 20 = 120/20. (left-side: the 20’s will be cancelled)
