Question

A box contains four soccer balls printed with numbers 112, 121, 211. 222. A footballer chooses one ball at random. Let A₁ be the event that the first digit of the printed number of the ball chosen is 1. Similarly, A₂ and A₃ denote that second as well as third digit of the printed number is 1. The events A₁,A₂, and A₃ are:
1. independent events
2. dependent events
3. pairwise independent events
4. mutually exclusive events

Answer 1

Correct Answer - Option 3 : pairwise independent events

Explanation

The events are called pairwise independent if any two events in the collection are independent of each other, while saying that the event are mutually independent

(or collectively  independent) it means that each event is independent of any combination of other events in the collection.

∴ Events, A₁, A₂, and A₃ are pairwise independent events
