Find the specified probability. The number of loaves of rye bread left on the shelf of a local bakery at closing (denoted by the random variable X) varies from day to day. Past records show that the probability distribution of X is as shown in the following table. Find the probability that there will be at least three loaves left over at the end of any given day: X 0 1 2 3 4 5 6 P(X=x) 0.20 0.25 0.20 0.15 0.10 0.08 0.02
