Answer:
41.8%
Step-by-step explanation:
From the table, the total number of female patients is given as 335. On the other hand, the total number of female patients with type-O blood is given as 140. The probability that a randomly selected female patient will have type-O blood can be calculated as;
the total number of female patients with type-O blood/the total number of female patients
140/335 = 0.4179
As a percentage this becomes;
0.4179 * 100 = 41.8%
Therefore, the percentage of female patients with type-O blood is 41.8%
