SUMMARY
The probability that the least number drawn from three chits, numbered 1 to 7 and drawn with replacement, is 5 is calculated as 19/343. This result is derived by ensuring that at least one of the chits drawn is a 5, while also confirming that no number drawn is less than 5. The correct interpretation of the problem emphasizes that all drawn numbers must be 5, 6, or 7, leading to the conclusion that the probability is based on these conditions.
