Video transcript
The probability of getting 53 Mondays or 53 Saturdays in a leap year is due to the extra day in February. 53 Mondays happen if the first day of the year is a Monday or if one of the first two days is a Monday, giving a probability of 2/7. 53 Saturdays happen similarly. Since each can occur separately, the combined probability is 4/7.
