David throws a die 10 times and the following are outcomes 2, 5, 6, 6, 1, 5, 4,1, 4, 6, 5. The mean of the above observation is:
(a) 3
(b) 4.5
(c) 5
(d) 45
(e) None of these
Answer: (b)
Explanation
\[mean=\frac{sum\,of\,observation}{Total\,number\,of\,observation}\]
\[=\frac{2+5+6+6+1+5+4+1+4+6+5}{10}=4.5\]
