1. What is the mean of the first five naturals? (a) 5 (b) 2. (c)3 (d) 4 ​

Answer 1

Solution:

First five natural numbers 1,2,3,4,5

= $\boxed{ \tt \pink{mean = \frac{sum \: of \: observations }{no. \: of \: observations} }} \: \star$

So, just put the values now..!!

=> $\tt{Mean = \dfrac{1 + 2 + 3 + 4 +5}{5}}$

=> $\tt{Mean = \dfrac{15}{5}}$

=> $\bf{Mean = 3}$

Therefore, the mean is 3, so option c) is the right answer!!
