Bin A contains six cubes and two tetrahedrons, while Bin B contains three cubes and four tetrahedrons. If a shape is drawn at random from Bin A and placed in Bin B and then a shape is drawn at random from Bin B, what is the probability that the second shape chosen is a cube?

The probability that a cube is drawn from Bin A is 6/8.

 

Now, there are 4 cubes and 4 tetrahedrons in Bin B.

The pobability that a cube is drawn from Bin B is 4/8.

 

The final probability is  (6/8) x (4/8)  =  your answer
