The number of ways three different natural numbers cab be drawn from the set `{1, 2, 3, 4,……….., 10}`, if minimum of the chosen numbers is smaller than 4, is

Write 4 rational number smaller than -3 .

The number of ways to choose 7 distinct natural numbers from the first 100 natural numbers such that any two chosen numbers differ atleast by 7 can be expressed as ""^(n)C_(7) . Find the number of divisors of n.

The number of ways to choose 7 distinct natural numbers from the first 100 natural numbers such that any two chosen numbers differ atleast by 7 can be expressed as ""^(n)C_(7) . Find the number of divisors of n.

Three numbers are chosen at random without replacement from {1,2,3,....10}. The probability that the minimum of the chosen number is 3 or their maximum is 7 , is:
