Answer 4

There is total of 30 sodas in the cooler, and a chance of 18/30 or 3/5 that the first choice will be a gingerale. With 17 gingerales and 12 lemon-lime drinks left in the cooler, there are 17 choices in 30 that second choice will be a gingerale. The product of the two choices is: 3/5x 17/30 = 51/150 or 17/50
