A new surgery is successful 80% ?of the time. If the results of 9 such surgeries are randomly sampled, what is the probability that at least 7 of them are successful? Carry your intermediate computations to at least four decimal places, and round your answer to at least two decimal places.


We have a binomial distribution with n = 9 and p = 0.8

P(X = s) => 9Cs(0.8)^s(0.2)^(9 - s)

More than 7 successes => either 8 or 9 successes

P(X = 8) => 9C8(0.8)^8(0.2)?

P(X = 9) =>...
