Question 2 • College Prep Math B - IC26
Each of the 24 digits has two equally likely possibilities, so there are 2²⁴ possible sequences. To have exactly 12 zeros, choose which 12 of the 24 positions contain zeros: there are (24 choose 12) = 2,704,156 such sequences. Thus the probability is 2,704,156 ÷ 16,777,216 ≈ 0.1612, which matches choice D.
