If the probability that A and B will die within a year are p and q reapectively , then the probability that only one of them will be alive at the end of the year is :

The probabilities that A and B will die with in a year are p and q respectively, then the probability that only one of them will be alive at the end of the year is -

If the probabilities of two dogs A and B dying within 10 years are respectively p and q, then the probability that at least one of them will be alive at the end of 10 years is

The probability that a man A will be alive for 20 more years (3)/(5) is and the probability that his wife will be alive for 20 more years is.The probability that only one will be alive at the end of 20 years is

The probability that a man will be alive for 10 more years is 1/4 and the probability that his wife will alive for 10 more years is 1/3 . The probability that none of them will be alive for 10 more years, is

A and B appear for interview. The probability of their selection is : 1/2 and 1/3 respectively. Find the probability that only one of them is selected.

The probability that a man will live 10 more years is 1//4 and the probability that his wife will live 10 more years is 1//3 . Then the probability that neither will be alive in 10 years, is
