When you talk days of the week there are only seven days named. So the odds of being on any one day are 1/7.
If the three are to all be the same day (Wednesday) then it is the joint probability of every one being on that day so it is 1/7 x 1/7 x 1/7 .
That equals 1/343 (same as for any day that you choose at random).
i don't know what part B was since it is missing

This is an impossible question to answer because 3 strangers could be born on entirely different years and the days change in different years. The probability wouldn't be accurate.
