The probability of meeting a random person who has the same birthday as you is 1/365 , which is approximately 0.27%. what is the probability that the 25th person you meet is the first person who has the same birthday as you?

The required probability (P) is :

Step-by-step explanation:

Probability of meeting random person who has same birthday as you =

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

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,

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
