None of these​

Answer 1

We know,

• First 10 whole number are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

$\bf{Mean = \frac{0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9}{10} } \\ \\ \frak{\: \: \: \: \: \: \: \: \: \: = > \frac{45}{10} \: \: \: \red{\sf{= 4.5}}}$

Hence,

• Option (A) is correct.

Answer 2

Step-by-step explanation:

First 10 whole numbers are 0,1,2,3,4,5,6,7,8,9....

$mean = \frac{sum \: of \: all \: observatons}{total \: no \: of \: observation}$

=0+1+2+3+4+5+6+7+8+9/10

=40/10=4.
