Base info: 40% are red, 30% are white, 20% are blue, and 10% are green
9) 40% chance to get red, 10% chance to get green. 50% chance to get one of either.
10) getting red: 40%
Getting blue: 20%
11) 80% (100% - 20% = 80%)
1/8 = 12.5%
12) 12.5% chance
13) 25% chance
14) 12.5 x 5 = 62.5
62.5% chance
Answer:

small cups=30
large cups=40
Step-by-step explanation:
let x be the number of small cups and y the number of large cups.
-Given that 10 more cups than small cups of lemonade were sold:

#Before the 10 more were sold, the number of x and y sold were equal>

The number of small cups sold was 30
#Since, the number of large cups was 10 more, y=x+10=30+10=40
