Algebra.Com's Answer #56787 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The numbers 1 to 10 are written on sheets of paper and placed in a hat. If two sheets are selected at random then find the following:\r \n" ); document.write( "\n" ); document.write( "The probabilit (both numbers are ODD with replacement)=(5/10)(5/10)=1/4 \n" ); document.write( "Note: \"with replacement\" assumes the first selection is replaced back into the hat before the second selection is made. \r \n" ); document.write( "\n" ); document.write( "A. 1/100 \n" ); document.write( "B. 1/4 \n" ); document.write( "C. 2/9 \n" ); document.write( "D. 1/5 \n" ); document.write( "------------------------- \n" ); document.write( "The probability (both numbers are ODD without replacement)=(5/10)(4/9)=2/9\r \n" ); document.write( "\n" ); document.write( "Note: \"without replacement\" assumes the first selection is NOT replaced back into the hat, but is held out, while the second selection is made. \r \n" ); document.write( "\n" ); document.write( "A. 1/5 \n" ); document.write( "B. 2/9 \n" ); document.write( "C. 1/4 \n" ); document.write( "D. 1/100 \n" ); document.write( "-----------------\r \n" ); document.write( "\n" ); document.write( "The probability (the first number is ODD AND the second number is EVEN without replacement) = (5/10)(5/9)=25/90=5/18 \n" ); document.write( "A. 1/4 \n" ); document.write( "B. 5/18 \n" ); document.write( "C. 2/9 \n" ); document.write( "D. 13/18 \n" ); document.write( "---------------- \n" ); document.write( "The probability \n" ); document.write( "(of selecting a 2 and then a 9, with replacement)=(1/10)(1/10)=1/100\r \n" ); document.write( "\n" ); document.write( "A 1/4 \n" ); document.write( "B. 5/18 \n" ); document.write( "C. 2/9 \n" ); document.write( "D. 13/18 \n" ); document.write( "-------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
