Answer 2

hey your answer

white balls=8
black balls=7
red balls=5
green balls=4
total no.of balls or total no.of possible out comes =8+7+5+4=24

1) Event(b)= getting a black ball when a ball is drawn at random
no.of. favourable outcomes=7(black balls)

p(b)=no.of. fav. outcomes/no.of.poss.out...
p(b)=7/24=0.291=29.1%

2)Event(g)=not green
no.of.favourable outcomes =24-4=20

p(g)=20/24=5/6=0.833...=83.3%

hope it helps...
