Question

the mean of 2/5,5/3,1/3,5/6,1/6 is​

Answer 1

Step-by-step explanation:

$\frac{2}{5} + \frac{5}{3} + \frac{1}{3} + \frac{5}{6} + \frac{1}{6}$

$mean = \frac{sum \: of \: observation}{total \: number \: of \: observation}$

$mean = ( \frac{2}{5} + \frac{5}{3} + \frac{1}{3} + \frac{5}{6} + \frac{1}{6} ) \div 5$

$= ( \frac{12 + 50 + 10 + 25 + 5}{30} ) \div 5$

$= ( \frac{102}{30} ) \div 5$

$= \frac{102}{150}$

$= \frac{17}{25}$
