They recently overhauled the probability and stats in 1231/1241, starting the 2011/2012 summer session. Apparently they made it a little more relevant, removed some of the dumb shit and added some nicer stuff which is actually applicable, so probably stuff that helps with MATH2089 and other stats courses down the road.
Apparently the 1231 summer session final that just happened had a whole question out of 4 on stats, so it's something that's becoming more prevalent in the course by the sounds of it.
