Algebra.Com's Answer #313916 by jim_thompson5910(35256) ![]() You can put this solution on YOUR website! Hint: Consider selecting 3 plants (from 18) and seeing how many ways there are to select 3 plants. This will equal the number of ways to select 15 plants (since 15+3 = 18). Note: this is assuming that order does not matter. \n" ); document.write( " |
