Autoattack = 100%

Infinity Edge makes you crit for 250% instead of 200%. That's 150%.

The Deceive crit is a bit weird (it's not just a 200% crit, it's a 140%/160%/180%/200%/220% crit, as was once stated clearly on this page). So that's 20%.

Masteries give another 10%.

100 + 150 + 20 + 10 = 280

278 x 1.2 = 336.
