Question
The probability that a non leap year selected at random will contain 53 sundays is ______.
Options
`1/7`
`2/7`
`3/7`
`5/7`
Solution
The probability that a non leap year selected at random will contain 53 sundays is `underlinebb(1/7)`.
Explanation:
A non-leap year has 365 days and therefore 52 weeks and 1 day.
This 1 day maybe Sunday or Monday or Tuesday or Wednesday or Thursday or Friday or Saturday.
Thus, out of 7 possibilites, 1 favourable event is the event that the one day is Sunday.
∴ Required probability = `1/7`.
