Algebra.Com's Answer #690465 by addingup(3677)![]() ![]() You can put this solution on YOUR website! The probability is, the problem tells you, that 20% of the 15 will wear their ties too tight. \n" ); document.write( "15*.2 = your answer -it's 3, you should be able to do 15 x 2 in your head, then move the product you get one decimal because it's .2, so 30 becomes 3. \n" ); document.write( " |
