Indian National Mathematical Olympiad students are invited to the International Mathematical Olympiad Training Camp (IMOTC), a one-month mathematics camp hosted by the Homi Bhabha Centre for Science Education in Mumbai. For first time participants, it usually extends from late April till the end of May, while it begins about 10-14 days later for senior participants. In this camp, the students are taught Olympiad mathematics and some other general mathematics. Four selection tests and two practice tests are held during this period and the top six students in the selection tests qualify to represent India in the International Mathematical Olympiad. The selected team of 6
Return period interest and formula_5 is the counting rate. If the return period of occurrence is 1 in 234 years (formula_5 = 0.0043) then the probability of no occurrence in ten years is In a given period of "n" years, the probability of a given number "r" of events of a return period formula_5 is given by the binomial distribution as follows. In the limit of :formula_11, such that formula_12 then Take where Given that the return period of an event is 100 years, So the probability that such an event occurs "exactly once" in 10 successive years is: Return period is
