Algebra.Com's Answer #641564 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! a. (10/22)(9/21)(8/20)=0.0779 (30/385) \n" ); document.write( "b. The denominator is 22*21*20*19 \n" ); document.write( "The numerator is 6 ways this can happen, which will contain the number 10*9*12*11 \n" ); document.write( "two red then two white would be 10/22 * 9/21 *12/20*11/19. \n" ); document.write( "The numerator is 71280 \n" ); document.write( "The denominator is 175560. The probability is 0.4060 \n" ); document.write( "c.When the first two are white, there are 20 flowers left. The probability that the third flower is red is 10/20 or 1/2. \n" ); document.write( " |
