BIrthday paradox problem

#1

Not able to understand the sample test case

hi @nayakashutosh99, what you have to do is to determine the minimum number of people required in the room so that two have same birthday with probability greater than or equal to ā€˜pā€™.
test case means that you need to have 23 people in the room so that the probablity that any two people out of them has birthday on the same date is more than 0.5.
this is more of maths problem than any ds or algo problem so think accordingly
if you find any difficulty then you can refer to my previous discussion at : Birthday Paradox
