Given; Two friends have the same birthday
To Find; the probability of two friends having a different birthday
Solution; A year has 365 days if it is not a leap year. If two friends have the same birthday then only on one day of the year it is possible
Probability of having same birthday =1/365
Probability if not occurring of an event is 1-probability of occurring
The probability that they have different birthdays =364/365
Hence the probability is 364/365
