# AQA S1 Probability

Announcements Posted on
Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. Hey guys
Revising for s1 and I am getting frustrated because on the probability questions (tables, tree diagrams etc) sometimes you would times the probability by the number of times it can happen, but sometimes you don't. An example is Q2 in Jan 2011 and Q5 in June 2011. Seems to be the same question, but the method is different.
Can anyone tell me why it is happening??

In the future, please link the papers if possible - saves people a lot of time

Which bits of those questions are you looking at? I'm guessing 2c, not sure which one for q5.
