If I were one of the students and it is certain that I'll be a member of the committee, then 3 more students are needed to be selected from the remaining 25 students. It can be done in C%2825%2C+3%29+=+2300 ways. Then 4 parents had to be selected from 37 parents. This can be done in C%2837%2C+4%29=66045. There are 
C%2863%2C+8%29+=+3872894697 ways of selecting 8 people out of 26%2B37+=+63 people.
The probability is then
2300%2A66045%2F3872894697+=+0.03922.
