let c = # of cheeseburgers

let h = # of hamburgers

c = 2h (The number of cheeseburgers sold was two times the number

of hamburgers sold.)

Jose surveyed the length of TV commercials (in seconds). Find, to 3 decimal places, the experimental probability that a randomly chosen TV commercial will last:

Length Frequency

0-19 17

20-39 38

40-59 19 20 to 39 seconds.

60+ 20 to 4

Here is my anwer:

experimental probability = relative frequency = $\frac{number of oserved occuerencies}{total number of oserved occuerencies}$

Total frequencies = 17 + 38 +18 + 4 = 78

P(20 to 39s) = 38/78 ≈0.487
