En el almacén se tiene una caja con 30 focos de igual forma y de colores. 15 son de color rojo, 10 de colorblanco, y 5 de color azul . Si se toman cinco focos al azar: a)La probabilidad de cada uno de los eventos elementales del espacio muestral S de este experimento.
b)Cuál es la probabilidad de que se saquen dos de color rojo, dos de color blanco y uno de color azul.
c)Calcule la probabilidad de que se saque a lo más dos de color azul.

The translation:  

In the warehouse, there is a box with 30 lights of the same shape and colors. 15 are red, 10 are white, and 5 are blue. If five bulbs are taken at random:

a) The probability of each of the elementary events of the sample space S of this experiment.

b) What is the probability that two red, two white, and one blue are drawn.

c) Calculate the probability that at most two are drawn of the color blue.

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.
