ITPEC IP October 2020 Question 3
ITPEC IP October 2020 — Question 3 of 100
There are 5 choices for chairperson and independently 5 choices for secretary, giving 5 × 5 = 25 combinations. Dual roles are allowed, so selecting one person for chairperson does not remove that person from the secretary choices.
Answer (d)
Why not others:
- 5 counts only one of the two roles
- 10 adds the choices instead of multiplying independent selections
- 20 would be 5 × 4 and applies only if one person could not hold both roles
Key rule: Use the multiplication principle for successive independent choices; allowing the same person in both roles keeps five choices at each stage.
