Official answer

If one of the seven days of the week is chosen uniformly and “weekend” means Saturday or Sunday, two outcomes qualify. The probability is 2/7, approximately 28.57%.

This samples day-of-week names, not an unspecified date range. A finite calendar range may contain unequal numbers of each weekday, and a different weekend convention changes which days count.
