| Algebra.Com's Answer #199485 by stanbon(75887)      You can put this solution on YOUR website! A postal carrier distributes letters, ads, and magazines. The break down of deliveries is:\r \n" ); document.write( "\n" ); document.write( "Delivered to / Letter / Ads / Magazines /Total \n" ); document.write( "Homes /775 / 880 /270 /1925 \n" ); document.write( "Business /485 /417 /180 /1082 \n" ); document.write( "Total /1260 /1297 /450 /3007 \n" ); document.write( "--------------------------------------------- \n" ); document.write( "Questions \n" ); document.write( "A What is the probability that it was an ad? = 1297/3007 \n" ); document.write( "------------------------------------------------------------- \n" ); document.write( "B What is the probability that it was an ad delivered to a home? = 880/3007 \n" ); document.write( "------------------------------------------------------------- \n" ); document.write( "C What is the probability that it was an ad or it was delivered to a home? \n" ); document.write( "= P(ad)+P(home)-P(ad and home) = (1297+1925-880)/3007 = 2342/3007 \n" ); document.write( "======================================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
