Over a weekend, Ruth counted the number of single scoop ice creams ordered at her store. She tracked the flavors and the day on which it was ordered. The probability that an ice cream was cookie dough is 0.8, the probability that it was ordered on a Saturday
is 0.5, and the probability that it was cookie dough and was ordered on a Saturday is 0.4.
What is the probability that a randomly chosen ice cream was cookie dough or was ordered on a Saturday?

d.) 48 units

step-by-step explanation:

is there supposed to be a picture here?

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
