Of a physician's clients, 120 have health insurance or prescription drug coverage or both. If 40 of the clients do not
have prescription drug coverage, how many of the clients have both health insurance and prescription drug coverage?
(1) A total of 92 of the clients have health insurance.
(2) Of the 120 clients, 28 do not have health insurance.
health insurance =H;
prescription drug =P;
no. of clients with only H= a
no. of clients with only P=c
no. of clients with both H and P=b
hence we have
we need to find b.
1) A total of 92 of the clients have health insurance.
2) Of the 120 clients, 28 do not have health insurance.
hence as above b is calculable.
hope this helps..!!
