Question 1118494

 *[illustration StocksBondsMMVenn.jpg]


22 are all three so that goes in the center.  36 are Stocks and Money Market, but you have already accounted for 22 of those (the ones in the center) so 36 minus 22 = 14 goes in the space common to Stocks and Money Mkt.  Calculate the Stocks/Bonds and the Bonds/Money Mkt the same way.  Then, add the number that are Stocks/Bonds, the number that are Stocks/Money Mkt, and the number that are all three.  Subtract that from the total invested in Stocks to get the number invested ONLY in Stocks.  Calculate the only Bonds and only Money Mkt the same way.  Add up all of the numbers you have in the chart and subtract from 200 to get the number invested in None (the number not in any of the circles.


The probability of anything is the number of possible successful outcomes divided by the total number of outcomes.  The denominator for all three of your questions is 200.  And you can count the number of successes for each of the questions as well as I can.  The rest is just calculator work.


By the way, you should check all of the numbers that I entered into the chart above.  Sometimes I make arithmetic errors, so you would be foolish to trust me.
