Answer:
0.1612
Explanation:
We are given that there are 24 binary digits .
We are supposed to to find the probability that exactly half of the digits are 0.
Probability of success p (getting half of 24 i.e. 12 digits is 0 ) = 0.5
Since the sum of the probabilities is 1 .
So, probability of failure q = 1-0.5 = 0.5
Formula :

So, n = 24
r = 12
p = 0.5
q=0.5
Substituting the values we get :




Thus the probability of exactly half of the digits are 0 is 0.1612
Hence Option D is correct .
