Answer 1

Q13)

Sol^{n-​​​​​​} In the Venn Diagram, the rectangle represents the total number of families which is equal to 9+4 = 13 families.

The shaded area represents the families who own a pet which is equal to 4 families and so 9 families do not own a pet.

So the correct option is-

a) Of 13 families, 4 own a pet. The shaded area represents the families that own a pet.

Q14)

Solⁿ- If two events A & B can't occur at the same time, they are disjoint.

Disjoint events - Two events, A and B, are disjoint if they do not have any common outcomes. In other words, they are mutually exclusive.

For example, a football game can’t be held at the same time as a rugby game on the same field.
