Answer:
243 ways
Step-by-step explanation:
Calculating the number of posible outcomes:
We have n trials.
Each trial has m possible outcomes.
The total number of outcomes is:
[tex]T = m^{n}[/tex]
In this question:
5 questions, that is, 5 trials, so [tex]n = 5[/tex]
Each question has 3 options(True, false or unanswered). So [tex]m = 3[/tex]
How many ways?
[tex]T = 3^{5} = 243[/tex]
