If the probability that a man aged 60 will live to be 70 is 0.65 what is the probability that out of 10 men now 60 at least 8 will live to be 70 ?

p is the probability that a man aged 'x' years will die in a year. Find the probability that out of 'n' men A_(1) , A_(2) ,….., A_(n) each aged x, A_(1) will die in a year and will be the first to die.

The probability that a man aged x years will die in a year is p . The probability that out of n men A_(1),A_(2),A_(3),….A_(n) each aged x , A_(1) will die and be first to die is :

The probability that a man who is 45 years old will be alive till he becomes 70 is 5/12 . The probability that his wife who is 40 years old will be alive till she becomes 65 is 3/8 . What is the probability that, 25 years hence, : at least one of them will be alive.

The probability that a 50 year old man will be alive at 60 is 0.83 and the probability that a 45 year old woman will be alive at 55 is 0.87 Then The probability that both will be alive is 0.7221 At least one of them will alive is 0.9779 At least one of them will alive is 0.8230 The probability that both will be alive is 0.6320

The probability that a man who is 45 years old will be alive till he becomes 70 is 5/12 . The probability that his wife who is 40 years old will be alive till she becomes 65 is 3/8 . What is the probability that, 25 years hence, : exactly one of them will be alive.

The probability that a man who is 45 years old will be alive till he becomes 70 is 5/12 . The probability that his wife who is 40 years old will be alive till she becomes 65 is 3/8 . What is the probability that, 25 years hence, : the couple will be alive.
