Question

Help please about this math work

Answer 1

There is a 46% chance of a female patient having type-O blood

Answer 2

19.6

Explanation:

The question is slightly ambiguous. The data tells us that the number of females with O blood is 140.

I think you take this out of the entire population which is 714

The % is (140 / 714) * 100 = 19.61%

I wouldn't bet on these numbers being accurate.
