Algebra.Com's Answer #454276 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! 1.The probability that a person is a college graduate is 0.41 and that he/she has high blood pressure is 0.37. \n" ); document.write( "Assuming that these two events are independent, the probability (to four decimal places) that a person selected at random is a college graduate OR has high blood pressure is. \n" ); document.write( "------ \n" ); document.write( "The events are independent but the compound event is an \"OR\" event. \n" ); document.write( "P(A OR B) = P(A)+P(B)-P(A and B) \n" ); document.write( "---- \n" ); document.write( "You are give P(A) = 0.41 and P(B) = 0.37 but you are told nothing that \n" ); document.write( "enables you to evaluate P(A and B) \n" ); document.write( "---- \n" ); document.write( "Ans: insufficient information. \n" ); document.write( "===================================\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "2.The probability that a corporation made profits in 2005 is 0.64 and the probability that a corporation made charitable contributions in 2005 is 0.33.
