Hey guys I have a probability problem that I can not solve. In the problem we have 10 boys and 5 girls.

We take all of them(15 people) and we place them next to each other(in a row). What is the probability that at least 1 girl is placed next to another girl?

At first I thought it would be easier to find the possibility that there is no girl placed next to another girl so the original possibility I am asked to find will be 1 minus this possibility. However I sill find it difficult to solve.
