In a non - leap year, what is the probability that the last day of the year stars with a 't'?

According to the probability theory we have to give the total number of days starting with letter T by the total number of days in a way to get the probability of being a day which starts with letter T

Number of days starts with letter T= 2(Thursday and Tuesday)

Number of days in a week is 7.

So the probability will be 2/7.
