To find the probability that exactly 9 patients are successful, we can use the binomial probability formula. The formula is P(x=k) = (n choose k) * p^k * (1-p)^(n-k), where n is the number of trials, k is the number of successful outcomes, and p is the probability of success. Plugging in the values, we have P(x=9) = (12 choose 9) * 0.7^9 * (1-0.7)^(12-9). Calculate this expression to find the probability that exactly 9 patients are successful.
