To find the probability that a client is subscribed to TV service or Internet, we need to add the percentages of clients who are subscribed to TV and Internet, and subtract the percentage of clients who are subscribed to both (since we don't want to count them twice). So, P(TV or Internet) = P(TV) + P(Internet) - P(TV and Internet) = 0.28 + 0.64 - 0.22 = 0.70. Therefore, the answer is B.
