A bag has 4 red lollipops, 3 orange lollipops, 3 black lollipops, and 1 yellow lollipop. You randomly pull a lollipop from the bag, put it back, and then pull out another one. What is the probability of getting a red and then a black? Write your answer as a fraction.

answer: procent 54 wynosi 33,33%

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
