Algebra.Com's Answer #297108 by robertb(5830) You can put this solution on YOUR website! P(A in Math OR A in Stats) = P(A in Math) + P(A in Stats) - P(A in Math OR A in Stats) = 0.51 + 0.67 - 0.41 = 0.77, the probability that she receives an A in statistics or mathematics (or both). \r \n" ); document.write( "\n" ); document.write( "It's called the General Addition Rule of Probability. No need for Venn Diagrams here. \n" ); document.write( " |
