microfracture knee surgery has a 75% chance of success on patients with degenerative knees. The surgery is performed on 5 patients. Find the probability of the surgery being successful on less than 3 patients

Here is the easiest way to do this problem.
Use a binomial probability table.
n = 5
x = 0, 1, 2
p = .75
Add P(0), P(1), and P(2). This will be your probability.
I hope this helps.
