If a seed is planted, it has a 65% chance of growing into a healthy plant.
If 11 seeds are planted, what is the probability that exactly 3 don't grow?
~~~~~~~~~~~~~~
Exactly 3 of 11 don't grow means that exactly 8 of 11 do grow.
It is a binomial distribution probability problem.
- number of trials n = 11;
- number of success trials k = 8;
- Probability of success on a single trial p = 0.65.
We need calculate P(n=11; k=8; p=0.65).
