Answer 2

Answer:

Step-by-step explanation:

Riya may have any one of 365 days of the year as her birthday. Similarly, Kajal may have any one of 365days as her birthday.

A total number of ways in which Riya and Kajal may have their birthday are:

365 x 365

Then Riya and Kajal may have the same birthday on any one of 365 days.

Therefore the probability of Riya and Kajal may have same birthday are:

= 365/(365 x 365)

= 1/365
