That is the same as asking 15C10 which is 3003.
It is 15! divided by (15-10)!(10!)
This is
15x14x13x12x11 divided by 5x4x3x2x1
or divided by 120
or 360360=3003

In a subset each element of the original may or may not appear - a choice of 2 for each element; thus for 3 elements there are 2 × 2 × 2 = 2³ = 8 possible subsets.

The empty set has only one subset: itself. It has no proper subsets.
A set with n elements has 2n subsets. The number of proper subsets is one less, since 2n includes the set itself.
An element doesn't have subsets. Sets can have subsets.
A set with N elements has 2N subsets.
Two. The set {x} has the subsets {} and {x}.
That means, figure out how many different subsets a set has. In general, if a set has n elements, it has 2n different subsets.

We do not know what is in set A.
In a subset each element of the original may or may not appear - a choice of 2 for each element; thus for 3 elements there are 2 × 2 × 2 = 2³ = 8 possible subsets.
If you have a set of 6 elements, you can make a total of 26 different subsets - including the empty set and the set itself.
64. You can use Pascal's triangle to figure out how many subsets have no elements, one element, two elements and so on. For this particular one, you will have 6 subsets with one element, 15 with two, 20 with three, 15 with four, 6 with five and only one each of all six and none at all.

There are 2100 = 1.268*1030 or 1,268 octllion subsets with an odd number of elements.
No. Pumpkin is made up of many different molecules composed of different elements.
