Let x be the total number of clients of this company.
Hence, the total numbers of times they have used the insurance
= 0 × ( 1 0 0 4 0 ) x + 1 × ( 1 0 0 3 0 ) x + 2 × ( 1 0 0 2 0 ) x + 3 × ( 1 0 0 1 0 ) x
= x
Therefore, the average times of insurance claims = x x = 1 .
In other words, in the past year, the clients have averagely used their insurance only once.
