Microfracture knee surgery has a 75% chance of success on patients with degenerative knees. The surgery is performed on three patients. Find the probability of the surgery being successful on exactly two patients. State what q is equal to.
Answer : Given : The probability of success $(p) = 0.75$ Sample size $(n) = 3$ Solution : The probability of failure : $$\therefore q = 1 – P \ = 1 – 0.75 \ = 0.25$$ → The probability…
