Answer 1

Answer:

this is true make me brainlest

Answer 2

Answer:

Given,

A= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

A1= {1, 2, 3, 4}.

A2= {5, 6, 7}.

A3= {4, 5, 7, 9}.

A4= {4, 8, 10}.

A5= {8, 9, 10}.

A6= {1, 2, 3, 6, 8, 10}.

To Find,

which out of the given sets is the partition of the main set A.

Solution,

We understand that partition is dividing one thing into two or more things without losing any part.

We see, that set A1, A2, and set A5 is the partition of set A.

Similarly, set A3 and set A6 are also the partition of set A.

Hence, we have two partitions, Set A1, A2, A5, and set A3, A6.
