    the expected number of claims within a year is 10

    Step-by-step explanation:

    since the life expectancy of each man is independent from others, then the random variable X = number of man of 50 years who die within a year, follows a binomial distribution. Thus the expected value of X is given by

    E (X) = n*p

    where

    p = probability that a man of age 50 dies within a year = 0.01

    n = number of policies on men of age 50 = 1000

    replacing values

    E (X) = n*p = 0.01 * 1000 = 10

    therefore the expected number of claims within a year is 10
