Random sampling is random, opportunity sampling is using people available... that's what i thought anyway

I believe that the answer was thought out in this way: opportunity sampling is when whoever volunteers is chosen to take part whilst random sampling is when anyone is used (e.g. when in a natural setting you can't ask people to participate or results are affected).
