Question: what is the probability of having 52 sundays in a non leap year?
Answer: 6/7 or 0.86 is probability for 52 Sundays in a non-leap year. The odd day may be either Sunday, Monday, Tuesday, Wednesday, Thursday, Friday or Saturday. Therefore, the total number of possible outcomes or elements of a sample space is 7. 0.86 is probability for 52 Sundays in a non-leap year.
