Draw the following probability tree |dw:1399421360137:dw|
jimthompson5910 (jim_thompson5910):
The values on the very right are the result of multiplying each branch For instance this value 0.087 |dw:1399421814353:dw| is found by multiplying the values along this branch |dw:1399421830550:dw| so 0.58*0.15 = 0.087
