1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
The Failures In Time (FIT) rate of a device is the number of failures that can be expected in one billion (10 9) device-hours of operation [17] (e.g. 1,000 devices for 1,000,000 hours, or 1,000,000 devices for 1,000 hours each, or some other combination).
In general, if an increase of x percent is followed by a decrease of x percent, and the initial amount was p, the final amount is p (1 + 0.01 x)(1 − 0.01 x) = p (1 − (0.01 x) 2); hence the net change is an overall decrease by x percent of x percent (the square of the original percent change when expressed as a decimal number).
The economic costs of traffic congestion have increased 63% over the past decade, and despite the declining traffic volumes caused by the economic downturn, Americans still waste more than 2.8 billion US gallons (11 million cubic metres) of fuel each year as a result of traffic congestion. [40] Motorists also waste 4.2 billion hours annually ...
As of February 12, 2025, 310 miles of the parkway had reopened. The estimated repair cost was between $1 and $2 billion, and some work was expected to take two to three years. [94] The estimated cost to repair all damaged roads in Western North Carolina was $5 billion, $500 million of that for U.S. Route 19W [95] and $1 billion for I-40. [96]
A light-year is the distance light travels in one Julian year, around 9461 billion kilometres, 5879 billion miles, or 0.3066 parsecs. In round figures, a light year is nearly 10 trillion kilometres or nearly 6 trillion miles. Proxima Centauri, the closest star to Earth after the Sun, is around 4.2 light-years away. [89]
The number of deaths per passenger-mile on commercial airlines in the United States between 2000 and 2010 was about 0.2 deaths per 10 billion passenger-miles, [96] [97] while for driving, the rate was 1.5 per 100 million vehicle-miles for 2000, which is 150 deaths per 10 billion miles for comparison with the air travel rate. [16] [98] [99] [100]
In 2014, Los Angeles–Long Beach–Anaheim placed third among the largest exporters in the United States (shipment totaling to $75.5 billion). The metro accounted for 40.8 percent of California's merchandise exports, mainly exporting computer and electronic products ($18.6 billion); transportation equipment ($15.3 billion) and chemicals ($5.6 ...
