You can put this solution on YOUR website! Assume that we have ten people. Find the probability that at least two of ten people were born on the same day of the year.
This ia a binomial problem.
# of trials =10
Prob. of success = 1/365
Number of sucesses desired is at least 2.
Using a TI-83 calculator get the following:
Prob = 1-binomcdf(10,1/365,1)=0.000333
