A jar contains 5 pink and 8 navy marbles. A marble is drawn at random. What is the theoretical probability of NOT drawing pink?

8/13 = 0.53 (likely)

8 (navy marbles) over the total amount of marbles = 0.53

0=impossible

between 0 and 0.25 = likely impossible

between 0.25 and 0.50 = less likely

0.50 = equal, even, or same

between 0.50 ans 0.75 = likely

between 0.75 and 1 = most likely

1 = certain

5 pink + 8 navy = 13 total marbles

not picking pink would mean you would need to pick a navy one which would be 8/15 probability
