In the SuperLottery, three balls are drawn (at random) from ten white balls numbered from 1 to 10, and one SuperBall is drawn (at random) from ten red balls numbered from to 11 to 20. When you buy a ticket, you choose three numbers from 1 to 10 and one number from 11 to 20. If the numbers on your ticket match at least two of the white balls or match the red SuperBall, then you win a super prize. What is the probability that you win a super prize?

Step-by-step explanation:
Maya has 120 caramel apples to sell.
Each caramel apple is covered with one topping.
1/5 of the caramel apples are covered with peanuts.
1/3 of the caramel apples are covered with chocolate chips.
3/10 of the caramel apples are covered with coconut.
The rest are covered with sprinkles.
find:
How many caramel apples are covered with sprinkles?
120 = (1/5 * 120) + (1/3 * 120) + (3/10 * 120) + sprinkles
120 = 24 + 40 + 36 + sprinkles
sprinkles = 120 - 24 - 40 - 36 = 20
therefore,
there are 20 caramel apples covered with sprinkles.
