Could you generate a complete set of 6 number combinations from 45 numbers ?


If you have a set of 40 numbers how do you calculate the number of all the possible combinations of 5 numbers from the set?

By making a number tree that could have as many as 1,000,000 combos.


How many combinations of 4 numbers can be made from the set of numbers 246789?

If the numbers are allowed to repeat, then there are six to the fourth power possible combinations, or 1296. If they are not allowed to repeat then there are only 360 combinations.

The answer is 8C7 = 8. In each combination, you will miss out one of the 8 from the whole set.


How do you find out a median of a set of numbers?

If you order the numbers from the higher to the lowest, the median is the number separating the lower half of the numbers from the higher half of the numbers in the set. If you have an odd number of elements in the set then the median is in the middle of this descending ordered numbers. If you have an even number of elements then, in order to determine the median, you calculate the mean of the two middle values.

Is the set of prime numbers is well defined or not and why?

The set is well defined. Whether or not a given integer belongs to the set of prime numbers is clearly defined even if, for extremely large numbers, it may prove impossible to determine the status of that number.

How many 4 number combinations can made from four numbers?

Like 1235 or 8067? If you allow leading zeros, then 10 000. If you disallow leading zeros, then 9 000. * * * * * Those are the numbers of PERMUTATIONS, not COMBINATIONS. In combinations the order does not matter, so 1234 = 4312 = 2314 etc. The number of combinations is (10*9*8*7)/(4*3*2*1) = 210. The question of leading 0s does not arise because there is no order to the set of numbers in the combination so there is no "leading".
