The probability that fewer than two out of seven stray dogs are unlicensed can be calculated using the binomial probability formula. The probability of 0 unlicensed dogs is (0.98)^7, and the probability of 1 unlicensed dog is 7*(0.02)*(0.98)^6. Adding these probabilities gives approximately 0.9921.
