Question 1100789: If a seed is planted, it has a 85% chance of growing into a healthy plant.
If 12 seeds are planted, what is the probability that exactly 4 don't grow? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! That is the same that 8 do grow.
12C8*0.85^8*0.15^4=0.0683
note
12C4*0.15^4*0.85^8 gives the same answer.
