For a certain species of bird, there is a chance of three in five that a fledgling will survive. From a brood of ten chicks, find the chance that more than one will survive.
Let p = survival chance = 3/5
Let q = non-survival chance = 2/5
P(less than one will not survive) = P(more than one will survive) = 0.006047 + 0.040311
This answer is wrong, however, as my textbook is answer says it is about 0.9989 or something similar to that. I know how to get that answer through using powers (1-0.4^10) but I don't understand how I didn't get the same answer from the table because I have used that method a lot with many other questions and I does work. Perhaps someone could explain what I have done wrong with me?
