A probability model includes P(1) = 310 and P(2) = 15. Which of the following probabilities could complete the model?
A: P(3) = 2/5
B: P(3) = 1/2
C:P(3) = 3/5
D:P(3) = 11/15

Similar. Congruent means identical — if they were to overlap, they’d be the exact same, while similar means that they’re different sizes but essentially the same (so if you were to change the size of one to the others size, you’d get the same identical shape).
