Probability

One study has reported that the sensitivity of the mammogram as a screening test for detecting breast cancer is 0.94, while itsspecificity is 0.97. It is estimated that in a particular population 5% of women aged 55-65 and 10% of women aged 66-75 have breastcancer.(i) What is the probability that a woman aged 60 does not have breast cancer given that her test result is positive?(ii) What is the probability that a woman aged 70 does not have breast cancer given that her test result is positive?(iii) What is the probability that a woman aged 70 does not have breast cancer given that her test result is negative?
