Answer 1

Step-by-step explanation:

First calculate total No. of balls i.e 7+5+8=20 balls

Now calculating probabilities;

P ( White ball )= No. of white balls/Total No. of balls

=7/20

=0.35

P ( Green ball )= No. of green balls/Total No. of balls

=8/20

=0.4

P ( Red ball )= No. of red balls/Total No. of balls

=5/20

=0.25
