the possibility of people investing in stock A is 0.40, the possibility of people investing in stock B is 0.15, and the possiblity of people investing in both stock is 0.05.
the question is what is the possibility of people investing in stock A first and will also invest in stock B.
I think the answer is 0.40*(0.05*0.40), because using a venn diagram, I can see that 0.05 is apart of the 0.40 circle. The possibility of people investing in stock A is 40% and 5% of these people, that is (0.05*0.40), will invest in another stock.
Am I right?
