2/7
Step-by-step explanation:
This is a very simple question worded very weirdly.
There are seven days in a week and only one Sunday in a week.
So the chance that one friend was born on the same week of the day is 1/7.
However, there are 2 friends and we are looking for the probability that at least one of these friends was also born on a Sunday, so we just add 1/7 + 1/7.
1/7 + 1/7 = 2/7, so the chance that at least one of the friends was also born on a Sunday is 2/7.
