The probability that a man aged x years will die in a years is p. The probability that out of n men M1, M2, M3...... Mn each aged n years Mk will die and be the first to die is?
Correct Answer: 1/n[1 - (1 - p)n]
Explanation:
∵ Probability that no man out of n men aged x years will die in a year = (1 - p)n
∴ Probability that out of n men at least one will die in a year = 1 - (1 - p)n .
When at least one, man dies, any one out of the n men may be the first to die
