Answer 1

Total number of questions = 5.

We have to select at least 2 from each part.

(1) Selecting 2 from A and 4 from B:

⇒ C(5,2) * C(5,4)

⇒ 10 * 5

⇒ 50.

(2) Selecting 3 from A and 3 from B:

⇒ C(5,3) * C(5,3)

⇒ 10 * 10

⇒ 100.

(3) Selecting 4 from A and 2 from B:

⇒ C(5,4) * C(5,2)

⇒ 5 * 10

⇒ 50.

Hence,

The total number of ways = 50 + 100 + 50

⇒ 200.

Hope this helps!
