What is a self-selected survey?
A self-selected sample survey is when the surveyer choses who he or she wants to ask the survey question to. So, the people surveyed are not random at all. One problem with this is that the surveyer can easily manipulate results by asking a group of people specifically to get a certain result. For example, if I wanted to do a survey about abortion, and I wanted the results to be in favor of my liberal views, I might only survey people in a liberal coffee shop in Seattle. This is a self-selected survey.

Likewise, if the children were picked inside a boys' school. If six children are picked at random from a large group of children with an equal number of boys and girls, then the answer is 6C2*(1/2)6 = 15/32 = 0.47, approx.
