The probability of atleast two out of a group of 50 people
share the same birthday is 97%
Probability of atleast two share the same birthday = 1 -
probability of all 50 have different birthdays
Probability of all 50 have different birthday
= 365/365 * 364/365 * 363/365 * ... * 317/365 * 316/365
= (365 * 364 * 363 * 362 * ... * 317 * 316)/36550
= 0.0296264
Probability of atleast two share the same birthday
= 1 - 0.0296264
= 0.9703735
= 97% approx.
Thus, the probability of atleast two out of a group of 50
people share the same birthday is 97%

Karan bought a little box of midget matches, each one inch in length. He found that he could arrange them all in the form of a triangle whose area was just as many square inches as there were matches. He then used up six of the matches, and found that with the remainder he could again construct another triangle whose area was just as many square inches as there were matches. And using another six matches he could again do precisely the same. How many matches were there in the box originally? Note that the match-box can hold maximum of 50 matches.
Which figure should be placed in the empty triangle? 6 7 7 6 8 6 6 ? 2 2 5 3 4 2 5 3
