I too got confused with the word "at least" I assumed that either a 1, 5 or 6 would constitute a win. Hmmm


This one is not an Official gmat question; It would be great, if those math experts writing such low-end stems firstly could get trained in SC. I lost much time trying to solve this one before I finally realized that the thing asked is actually different from what is meant. There is a parallelism issue with ‘at least’ here. Ideally, ‘at least’ is a redundant phrase and instead the stem should read as ‘if the player receives a five or a one on either side...’ This writing will include all the cases meant by the original stem and exclude those without 5 or 1 on either side.

In a game, one player throws two fair, six-sided die at the same time. If the player receives at least a five or a one on either die, that player wins. What is the probability that a player wins after playing the game once?

A. 1/3
B. 4/9
C. 5/9
D. 2/3
E. 3/4


at least based
so not getting 1 or 5 = 4/6
for two dice = 4/6 * 4/6 ; 4/9
1-4/9 = 5/9
IMO C
