A die is thrown 4 times. Getting a '6' is considered a success. The probability of getting at least one success is:
- A. 1 − (5/6)⁴
- B. 4/6
- C. (5/6)⁴
- D. 1 − (1/6)⁴
Answer: A) 1 − (5/6)⁴
Explanation: P(at least 1 success) = 1 − P(0 successes). n=4, p=1/6, q=5/6. P(X=0) = (5/6)⁴. Thus, probability is 1 − (5/6)⁴.
