Question 979411: The probability of a plant surviving in Kerry’s garden is 0.7. If she plants 19 new plants this year,
(a) what is the probability that at least 10 of them survive? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! The expected value is 13.3, so the probability should be high.
Use a binomial table with n=19 p=0.7 and look at the probability of what you DON'T WANT, the likelihood of n <10.
That is 0.0324.
Everything else up to 1 is what you DO want.
1-0.0324=0.9676, and that is the probability that at least 10 survive.
