1. Total of type AB divided by the total total number 33/714 divide that ( you want a decimal) = 0.04611... .046= 4.6%
2. 149/335 = 0.4179... = 41.8%

6.63% of all patients are blood type AB and 41.8% is the probability that a female patient will have type-O blood.

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

From the table:

Number of patients have type AB blood group = 15+18 = 33

Total number of patients = 714

Percent of all patients are blood type AB = (33/714)×100 = 6.621 ≈ 6.63%

Total number of female patient will have type-O blood = 140

Total number of female patients = 335

Probability that a female patient will have type-O blood = (140/335)×100

= 41.79 ≈ 41.8%

Thus, 6.63% of all patients are blood type AB and 41.8% is the probability that a female patient will have type-O blood.
