Answer:

2 out of 5

Step-by-step explanation:

I believe that 96/240 needs to be simplified until it cant anymore, an that is the probability because they both fit three, I will divide by three.

96/3=32

240/3= 80

<u>32/80</u>

  2

16/40 then because they both fit four, Ill do four.

4/10then 2 again

2/5 so, it is 2 out of five

please correct me if I am wrong, I was never good at probabilities, but I am better now.

Data :
(-3,-4) , (1,2)
Where
x₁ = -3 , x₂ = 1
y₁ = -4 , y₂ = 2
Formula for distance
D = √{(x₂-x₁)² + (y₂-y₁)²}
= √{(l--3)² + (2--4)²} = √(16+36) =√52 =7.21
