Explanation:
Empirical evidence supporting the belief that people who use tanning beds are three times more likely to develop skin cancer could include epidemiological studies that compare the incidence of skin cancer between tanning bed users and non-users, as well as longitudinal studies tracking individuals' tanning bed usage and subsequent development of skin cancer. Additionally, laboratory studies demonstrating the effects of ultraviolet radiation from tanning beds on skin cells and DNA damage could further support this belief.
