Q:

Solving a question related to (Independent Events) - Probability

One container holds 2 red cubes and 4 blue cubes and a second container holds 4 red cubes and 3 blue cubes.  One cube is selected at random from each of the two containers.  What is the probability that one of the cubes is red? 

A:

The answer to this question is: 

First Container: 

2 Red Cubes 
4 Blue Cubes 

Second container: 

4 Red Cubes 
3 blue Cubes  

There are 4 outcomes and they are as followed:
(R,R), (R,B), (B,R) And (B,B)
The question is asking about the probability of one cube is red out of the 2 containers.  
So, the probability will be: 
2/6*3/7+4/6*4/7 
= 11/21
