The probability of getting no more than 3 successful serves out of 6 can be calculated using the binomial probability formula. The probability of success on each serve is 0.64, and the probability of failure is 0.36. Calculate the probability for 0, 1, 2, and 3 successful serves and sum them up to get the total probability. This results in approximately 0.3732.
