Answer:

The required probability (P) is :

P =(\frac{364}{365})^{24}\cdot \frac{1}{365}

Step-by-step explanation:

Probability of meeting random person who has same birthday as you = \frac{1}{365}

Probability of meeting random person who do not has same birthday as you =

1-\frac{1}{365}=\frac{364}{365}

Now, to find the required probability that the 25th person you meet is the first person who has the same birthday as you = (Probability that the first 24 persons we meet did not have same birthday as you) × (Probability that the first 25 persons we meet has same birthday as you)

Therefore,

P =(\frac{364}{365})^{24}\cdot \frac{1}{365}
