Show answer and explanation

Correct answer: (A) 0.2508

Explanation

Use the binomial formula: $P(X=6)=\binom{10}{6}(0.6)^6(0.4)^4$.

The combination count is 210. Multiplying gives 0.250822656, which rounds to **0.2508, A**. The independence and fixed-probability model is the one intended by this probability question.
