Anyone would like to discuss edexcel S1 20th May 2011 paper?

Actually, the two answers are 0.038 and 0.02. There are four outcomes for the even number combination-- 444, 424, 244, 442, and two outcomes for the odd numbers-- 515, 155. 555 isn't an outcome in this case since the game would then be won in 2 spins not 3, and 0 is not part of the odd number combination 'cos it is essentially an even number.
