With each draw, the probability changes. \n" ); document.write( "Initially, blue has a 0.20 chance, and red has a 0.18 chance \n" ); document.write( "The first four should be blue, but then the probability of the next's being blue is <0.18. \n" ); document.write( "The next is red, then blue, then red,then red, then blue, then red. \n" ); document.write( "BBBBRBRRBR. \n" ); document.write( "Just keep computing the probability as the numerator and the denominator change with each draw. \n" ); document.write( "It is very close, and because blue is smaller, the changes are greater than for red. \n" ); document.write( "30/150 \n" ); document.write( "29/149 \n" ); document.write( "28/148 \n" ); document.write( "27/147 \n" ); document.write( "45/250 \n" ); document.write( "26/146 \n" ); document.write( "44.249 \n" ); document.write( "43/248 \n" ); document.write( "25/145 \n" ); document.write( "42/247 \n" ); document.write( " |
