A study determined that 4% of children under 18 years old lived with their father only. Find the probability that exactly 2 children selected at random from 10 children under 18 years old lived with their father only. The probability that exactly 2 of the 10 children under 18 years old lived with their father only is (Do not round until the final answer. Then round to the nearest thousandth as needed.)
