A study was conducted to determine whether there were significant differences between college students admitted through special programs (such as retention incentive and guaranteed placement programs) and college students admitted through the regular admissions criteria. It was found that the graduation rate was 92.6% for the college students admitted through special programs.

If 12 of the students from the special programs are randomly selected, find the probability that at least 11 of them graduated.
