HELP

Answer 2

I say B. 1/5

Answer 3

okay add all of the numbers together to get the total.
10+15+8+7=40
that's the total amount of balls
next the number of white balls which is know to be 8
your answer will be
(number of white balls)/(number of total balls)
8/40
simplify
4/20
2/10
1/5
your answer will be B
Hope this helps
