  1. Please post one question at a time and show your work. This is not a place where homework is done for you. There are other sites where that is done for a fee, but you won't learn much that way.

    1. The probability that the first person in a group of 1 has no match is 365/365. The probability that the second person is not a match to the first is 364/365. The probability that the third is not a match to either of the first two is 363/365. Continue this logic and the probability that there are no matches among 12 people is
    1*(364/365)*(363/365)*(362/365)*(361/365)*(360/365)*(359/365)*(358/365)*(357/365)*(356/365)*(355/365)*(354/365)= 0.833 (check my math)
    1-0.833 = 0.167 is the probability that there is at least one pair with the same birthday
