Answer: Our required probability would be
![(83)/(186)](https://img.qammunity.org/2020/formulas/mathematics/college/p6i2p3sdthxh23zuwgy99ulsduftetcxsd.png)
Explanation:
Since we have given that
Health problems Number of patients
Obesity 32
Diabetes 54
Heart problems 78
Eye problems 112
Dental problems 96
Total 372
We need to find the probability that a person chosen at random is a diabetic patient or an eye patient.
So, P(diabetic patient) + P(eye patient)
![(54)/(372)+(112)/(372)\\\\=(54+112)/(372)\\\\=(166)/(372)\\\\=(83)/(186)](https://img.qammunity.org/2020/formulas/mathematics/college/dsjza6b7gi65dyd2xjyz55txtcdcra2eay.png)
Hence, our required probability would be
