Question

Let a,b,c be three observations. The mean of these obsevation is (a)(a x b x c ) /3 (b) (a +b+c ) /3 (c)(a-b-c) /3 (d)( axb +c)/3​

Answer 1

Answer:

Correct option is

B

3

x+y+z

​

 

We know, Mean is given by,

$$\text{Mean}=\dfrac{\text{Sum of the elements}}{\text{Total number of elements}}$.

 

Given, x,y,z are three observations.

Then, Mean=  

3

(x+y+z)

​

.

Hence, option B is correct
