Determine if two sets are equivalent

100

What are equivalent sets?

If two sets have the same number of elements

200

Are the following 2 sets equivalent? Why or why not?

M= {26, 65, 98, 125, 654}

C= {90, 53, 76, 13, 890}

Yes, they are equivalent because both sets have the same number of elements.  

300

Are the following 2 sets equivalent? Why or why not?

P= {l, m, n, o, p, q}

W= {p, l, n, o, m}

No, they are not equivalent.

Set P cardinality= 6

Set W cardinality= 5

400

Determine if the set of number of letters in EDUCATION and the set B= {q, w, e, r, t, y, u, i, o} are equivalent.

Yes, they are equivalent.

500

Determine if Set B = {1, 4, 9, 16, 25} and D = {2, 3, 5, 7} are equivalent.

No, they are not equivalent. 

Set B has 5 elements

Set D has 4 elements

Determine if two sets are equal

100

When are sets equal?

Sets are equal if they contain the exact same elements and the same number of elements, regardless of their order.

200

Are the sets equal? Why or why not?

Set A = {6, 2, 9, 11, 3}

Set C = {6, 9, 2, 3, 14}

No they aren't because they do not have the same exact elements.

300

Set 1= {a, b, c, d, e, f, g}

Set 2= {c, e, a, b, f, g, d}

Yes they are equal

400

Create 2 sets that are equal (write on your whiteboard)

*teacher will check*

500

Are these sets equal? Why or why not?

Set 1= the number of whole numbers greater than 0 but less than 10

Set 2= the number of natural numbers less than 10

Yes, they are equal. They have the exact same elements.

TRUE or FALSE

200

If the number of elements in set C is 4 and the number of elements in set D is 4, then C = D.

What is FALSE?

300

If A = {x, y, z}, B = {s, t, u} then A n B is { }.

What is true?

400

All equivalent sets are equal sets.

What is FALSE?

500
