Complete the relative frequency distribution below.

Blood Group	Relative Frequency
O	​%
A	%
B	​%
AB	​%

Answer 1

Solution:-

Blood Group	Frequency	Relative frequency
O	15	37.5%
A	18	45%
B	4	10%
AB	3	7.5%
Total	40	100

$Relative.frequency = \frac{F}{\sum F}\ast 100$

$Relative.frequency (O)= \frac{15}{40}\ast 100$

$Relative.frequency (O)= 37.5$%
