Draw at random, with replacement, from the box of numbered tickets: 0,2,3,4,6 Fill in each blank with a whole number. If we draw at random, with replacement, 100 times and sum the draws, the smallest total we could possibly get is [a], and the biggest total we could possibly get is [b]. However, the sum is likely to turn out around [c], give or take [d] or so. Based on a normal approximation, there is about a [f]% chance that the sum will turn out to be at most 280. (Enter a whole number.)
