As we know:
10 red
8white
so total balls:
10+8=18
probability of white balls: white balls/ Total balls = 8/18
= 4/9
I hope you understood.

Probability is
No. of desired outcome/No. of total outcomes
In this case it will be 8/18
When we reduce it to lowest form it becomes 4/9 (as 2 is a factor of both 8 and 18)
So the correct option is
D) 4/9
