It means "intersection". It is an operation that is performed on sets or events. So if you have two sets A and B, then A ∩ B is the set of all elements in the sure event that are in A and in B. In other words, it is the event where A and B both happen.

â©is where two sets of numbers intersect. If Y1 = x and Y2 = X^2 they would â©at X = 0 and X = 1. If {x: -2 < x < 3} and {y: y = 2}, they intersect at 2. X â©Y = 2

It means "intersection", and it's used to indicate what two groups have in common. For example:
A: 1, 3, 5, 7, 9
B: 1, 2, 5, 6, 7
A â©B = 1, 5, 7

It is usually associated with set theory. The notation basically means "and". As in when an element of a set has characteristics that would put it in to separate subsets. Example, 2 is the only element of the sets of prime numbers â© even numbers.

The intersection of two sets, denoted Aâ©B ("A intersect B") is the set of all members contained in both A and B.

it means intersection...basically its whatever is in common to two things
