Answer 1

Answer:

4.6

Step-by-step explanation:

We are given the results of a survey of patients at a hospital of their blood type, categorized by their gender.

We are to find the percentage of patients with blood type AB among all patients.

Number of patients with blood type AB = 33

Total number of patients = 714

Percent of patients with blood type AB = $\frac { 3 3 } { 7 1 4 } \times 100$ = 4.6
