60% of the hockey players are from Eastern Canada and 40% are from Western Canada. 18% of the Eastern players and 12% of the Western players go on to play in the NHL. If a randomly chosen NHL player is selected, what is the probability that he is from Western Canada?

because it evaluates to 9.259 > 1.

Rework your expression and I am sure you'll get the right answer.

yes,y ou have it right
say there are 100 total
E in NHL = .18*60 = 10.8
W in NHL = .12*40 = 4.8
Total = 10.8+4.8 = 15.6
fraction W in total = 4.8/15.6
