In the smallstate lottery, three white balls are drawn (at random) from twenty balls numbered 1 through 20, and a blue superball is drawn (at random) from ten balls numbered 21 through 30. when you buy a ticket, you select three numbers from 1-20 and one number from 21-30. to win a prize, the numbers on your ticket must match at least two of the white balls or must match the superball. if you buy a ticket, what is your probability of winning a prize?

your answer is 125y5

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
