The empty set has only one subset: itself. It has no proper subsets.
The word mathematics has 11 letters; 2 are m, a, t. The number of distinguishable permutations is 11!/(2!2!2!) = 39916800/8 = 4989600.
A set with n elements has 2n subsets. The number of proper subsets is one less, since 2n includes the set itself.
It depends on the set x. If set x is of cardinality n (it has n elements) then it has 2n subsets.
There are 6 such subsets of B.
The words that can be made from the letters in hello are:ellhehellhohoeholelooh
If you include the empty set (as you should) there are 48.
An element doesn't have subsets. Sets can have subsets.
8 subsets
The word "many" can be formed from the letters NYMAG.
Only a set can have subsets, a number cannot have subsets.
Words that can be made from the letters in 'own' are nowand won.
5 subsets of 4 and of 1, 10 subsets of 3 and of 2 adds up to 30.
There is only one word that can be formed using all 7 letters provided. The word that is formed is "saltbox". There are many other words that can be formed using those letters that are 6 letters or less.
That means, figure out how many different subsets a set has. In general, if a set has n elements, it has 2n different subsets.
If the universal set contains N elements then it has 2N subsets.
Two. The set {x} has the subsets {} and {x}.
