Answer:

Regular: C & E

Irregular: A & B

Not a polygon: F & D

Step-by-step explanation:

A polygon is a close sided shape with no curves. Since F and D have curves they are not polygons. Regular polygons have side lengths which are all equal to each other. C and E are regular polygons. Irregular polygons are polygons whose sides have different values from each other. A and B are irregular.

There are 11 numbers on cards.

6 cards contain even numbers.

Answer: p(even) = 6/11

There is only one card with a 7. After the first card is picked and returned, there are 11 cards in the bag again.

p(even then 7) = p(even) * p(7) = 6/11 * 1/11 = 6/121

Answer: p(even then 7) = 6/121
