Question

In how many ways, can the students answer 3 true or false type questions in a slip test?

• A. 8

Answer 1

The correct option is A 8
(i) Assuming that the question Q1 is answered True, questions Q2 and Q3 can be answered as TT, TF, FT and FF in 4 ways.
(ii) Assuming that the question Q1 is answered
False, Q2 and Q3 can also be answered as TT, TF, FT,
and FF in 4 ways.
Thus, as each question has only two options
(True or False) in 2 ways, the number of ways of
answering these 3 questions in a slip test is
8 (2 x 2 x 2) possible ways.
