Based on the data, what is the probability that a randomly selected person age 40 or under rated the movie at 4 stars or 5 stars?

1/4

explanation:

ax=b

a would equal the value of a side on figure A

b would equal the value of the corresponding
side on figure B

x is the scale factor

here is what solving that would look like:

plug in the given values

divide both sides by to get by itself x=1/4

check with the other sides of the figures 6(1/2) =1.5

this is true so 1/4 is the correct answer
