A frequency

A frequency table of grades has five classes (A, B, C, D, F) with frequencies of 2,14,13,8, and 1, respectively. Using percentages, what are the relative frequencies of the five classes?

Correct answer:

p1 =  5.2632 %
p2 =  36.8421 %
p3 =  34.2105 %
p4 =  21.0526 %
p5 =  2.6316 %

Step-by-step explanation:

f1=2 f2=14 f3=13 f4=8 f5=1  s=f1+f2+f3+f4+f5=2+14+13+8+1=38  p1=100 sf1=100 382=38100 2=38200=19100%=5.2632%
p2=100 sf2=100 3814=38100 14=381400=19700%=36.8421%
p3=100 sf3=100 3813=38100 13=381300=19650%=34.2105%
p4=100 sf4=100 388=38100 8=38800=19400%=21.0526%
p5=100 sf5=100 381=38100 1=38100=1950%=2.6316%
