Question

Aditya and Sunny are two friends. They were born in 1880. What is the probability that they have the same birthday?

Answer 1

Answer:

$\large\boxed{\sf{\dfrac{1}{366}}}$

Step-by-step explanation:

Given that,

Aditya and Sunny are two friends.

They were born in 1880.

To find the probability that they have the same birthday.

We know that,

$\bold{Probability=\dfrac{ No. \:of\: favourable\: outcomes}{Total\:No. \:Of\: Possible\:Outcomes}}$

Now, we know that,

1880 is a leap year.

Therefore, there would be total 366 days.

Now, it is only possible to have their same birthday, if they were born on same day in same month.

So, we have all, possible outcomes = 366.

But, we need only one day for birthday.

So, favourable outcome = 1.

Hence, probability = 1/366.
