- Correcting the question :- The probability that A, B and C will live for more than 60 years is 1/ 2, 1/3 and 1/4 respectively. What is the probability that atleast 1 of them will be alive after 60 yrs of age?
Answer:-
Probability that atleast 1 person is alive = 1 - (Probability that all will die)
= 1 - ( Probability that A will die x Probability that B will die x Probability that C will die)
= 1 - ( (1 -1/2) x ( 1- 1/3) x (1 - 1/4))
= 1 - ( 1/2 x 2/3 x 3/4)
= 1 - (1/4)
= 3/4 - 4 years agoHelpfull: Yes(5) No(0)
