The probability of a completely random stranger's birthday being on a Saturday = 1/7
The probability of that event NOT occuring three times = (6/7)^3

probability= number of ways the outcome can happen ^ total number of possible outcomes
therefor probability= 1/7 (saturday is one day of the 7 day of the week)
= 0.14
and the probability of that NOT happening for the three people is = (6/7)^3
= 0.285

6/7*6/7*6/7 = 216/343 or about 63% likely.
