To find the probability that a small business has at least 2 job openings, we need to add together the probabilities of having 2 or 3 job openings. The probability of having 2 job openings is .08 and the probability of having 3 job openings is .25. Therefore, the probability of having at least 2 job openings is .08 + .25 = .33.
