Algebra.Com's Answer #736386 by Boreal(15235) You can put this solution on YOUR website! all 11 germinate is 0.6^11 or 0.0036 \n" ); document.write( "Only three will not germinate is same as 8 will germinate \n" ); document.write( "That is 11C8*0.6^8*0.4^3=0.1774 \n" ); document.write( "More than 5 will germinate is 0-5 won't germinate. That sum is 0.2465 so the answer is 1-0.2465 or 0.7535 \n" ); document.write( "Expected value is 11*0.6 or 6.6 \n" ); document.write( " |
