Dear Student,

Please find below the solution to the asked query:

We form our table from given information , As :
 

Number of times ( x )	1	2	3	4	5
Number of children( f )	10	23	45	18	4	$\sum _{}$f = 100
fx	10	46	135	72	20	$\sum _{}$fx = 283

Then ,

Mean  = $\frac{\sum _{}fx}{\sum _{}f} = \frac{283}{100}$ = 2.83                                                        ( Ans )
