mathematics

Question

Answer 1

With n variables, number of entries in the table = 2ⁿ
For  equal number of true and false values, you can choose any half values out of 2ⁿ as true and rest others will be automatically false.

So, from 2ⁿ places/values, we choose $\frac{2^{n}}{2}$=$2^{n-1}$ places for 'true' .

So (c) is answer.
