Answer:
Step-by-step explanation:
total no. of ball = 10
no. of red ball =3
no. of white ball=2
no. of green ball=5
(a)white ball
our favourable outcome is no. of whiteball
therefore probablity of white ball = 2/10 =1/5
(b) non red ball
i.e. total no. of non red balls = no. of white ball + no. of green balls
=2+5=7
therefore probablity of non red balls =7/10
