If the probability of machine failing during a day is 0.95. The probability of its working for four consecutive days without failing is?
Correct Answer: 0.0625
Explanation:
∴ Probability of machine failing during a day p = 0.95
∴ q = Probability of its working during a day = 1 - p = 1 - 0.95 = 0.05 Required probability = q4 = (0.05)4
= 0.00000625
