Coupon collector's problem. In probability theory, the coupon collector's problem refers to mathematical analysis of "collect all coupons and win" contests. It asks the following question: if each box of a given product (e.g., breakfast cereals) contains a coupon, and there are n different types of coupons, what is the probability that more ...
Introduced in March 2020, the 992 Turbo S has a twin-turbocharged 3.7-litre flat-6 engine rated at 478 kW (641 hp; 650 PS) and 800 N⋅m (590 lb⋅ft) of torque. [27] The engine is based on the 3.0 litre unit found in the Carrera models and has a slightly shorter stroke than that of the outgoing Turbo S engine.
The actual solution to this riddle is to add correctly (correct time, correct person and correct location) from the bank point of view which in this case seems to be the problem: First day: $30 in the bank + $20 owner already withdrew = $50. Second day: $15 in the bank + ($15 + $20 owner already withdrew) = $50.
Problem set. A problem set, sometimes shortened as pset, [1] is a teaching tool used by many universities. Most courses in physics, math, engineering, chemistry, and computer science will give problem sets on a regular basis. [2] They can also appear in other subjects, such as economics . It is essentially a list of several mildly difficult ...

The mathematical analysis of the problem reveals that the expected number of trials needed grows as O(nlog(n)). For example, when n = 50 it takes about 225 samples to collect all 50 coupons. Although the O-notation is correct as it is, I think it would be better to be consistent with the following article and write n ln n + \gamma n + O(1).
Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...
Zone 5 uses eight 2-digit codes (51–58) and two sets of 3-digit codes (50x, 59x) to serve South and Central America. Zone 6 uses seven 2-digit codes (60–66) and three sets of 3-digit codes (67x–69x) to serve Southeast Asia and Oceania. Zone 7 uses an integrated numbering plan; two digits (7x) determine the area served: Russia or Kazakhstan.
