# Probability of two people being born on the same day of the week

What is the probability of two people being born on the same day of the week?

I understand both of them individually have probability of 1/7 to be born on a certain day and that the two probabilities are independent of one another. So the answer could be 1/49. But that's a wrong answer.

Let $$A$$ be the day that the first person is born on and $$B$$ be the day for the second person.
\begin{align} Pr(A=B) = \sum_{i=1}^7 Pr(A=i)Pr(B=i)=\frac17 \end{align}
