You can put this solution on YOUR website! If you have a spinner with three even colours, red, green, blue, what is the tree diagram for three spins and the proability of getting 1 blue and then three green sectors from different spins?
-----
root column:: red, green, blue
1st branch column:: r, g, b to the right of each root entry
2nd branch column:: r, g, b to the right of each 1st branch column
3rd branch column:: r,g,b to the right of each 2nd branch column
-------
Total patterms:: 3^4 = 81
----
# of ways to be blue, green,green,green = 1
------
P(b,ggg) = 1/81
