41 years count 21.549.600 minutes if every year counts 365 days 41 * 365 * 24 * 60 = 21.549.60 More exact: in 41 there can be 10 or 11 leap years In the case of 10 leap years: (31 * 365 * 24 * 60) + (10 * 366 * 24 * 60) = 21.564.000 In the case of 11 leap years (the first year is a leap year): (30 * 365 * 24 * 60) + (11 * 366 * 24 * 60) = 21.565.440
14,975 approximately 365 x 41 = 14,965 then every four years is leap year so add 41/4 = about 10 14,965 + 10 = 14,975
41 122 365
365 since the pattern is times three minus one

The probability of at least 1 match is equivalent to 1 minus the probability of there being no matches. The first person's birthday can fall on any day without a match, so the probability of no matches in a group of 1 is 365/365 = 1. The second person's birthday must also fall on a free day, the probability of which is 364/365 The probability of the third person also falling on a free day is 363/365, which we must multiply by the probability of the second person's birthday being free as this must also happen. So for a group of 3 the probability of no clashes is (363*364)/(365*365). Continuing this way, the probability of no matches in a group of 41 is (365*364*363*...326*325)/36541 This can also be written 365!/(324!*36541) Which comes to 0.09685... Therefore the probability of at least one match is 1 - 0.09685 = 0.9032 So the probability of at least one match is roughly 90%
