As we learned

Discrete frequency distribution -

A representation of data in which each outcome is paired with its frequency is called a frequency distribution.

ex : x : 0 1 2 3 4 5

f : 2 4 4 6 4 5

-

Here mean A=5

Let the frequency of 8 be x. Then by the formula

or 18 = 3x; x = 6.

Option 1)

4

Option 2)

5

Option 3)

6

Option 4)

none of these
