I see many answers about getting an exact number of coin flip outcomes with a fair coin, and some about getting an exact number of coin flip outcomes with an unweighted coin (like this one) but I am curious about a the probability of at least a number of outcomes with an unfair coin.
If I have an unfair coin that gets tails with a probability of
P what is the probability that I get at least
N number of heads in
For instance, if my coin gets tails 60% of the time, what is the chance that I get at least 10 heads in 100 flips?
