It is: 43680/1456 = 30
Based on a 2000 hour work year it comes out to $21.84 per hour.
If order matters and a number cannot be repeated, then there are 16x15x14x13 = 43680 different combinations. If order does not matter then you must divide by the number of ways you can rearrage the same 4 numbers i.e. divide by 4x3x2x1=24 so you can select 4 numbers from a group of 16 in 43680/24 = 1820 ways. In mathematical terms there are 43680 permutations of 16 numbers taken 4 at a time and 1820 combinations of 16 number taken 4 at a time.
This is a permutation;16 P4. It is easy to calculate if you have statistics functions on your calculator. Otherwise, it is: 16!/(16-4)! = 43680.
The probability that the first four cards are face cards is (16/52)*(15/51)*(14/50)*(13/49) = 43680/6497400 = approx 0.0067
The easiest way to estimate yearly earnings -> hourly wage, presuming 40hrs a week, is to strip off the three 000's and divide by 2. Or, if you prefer, divide by 2,000. 82/2 = 41 per hour.
