Under the "cola" heading, to the right of "under 40 years of age," we find the count 20. This is the number of subjects who 1) prefer cola AND 2) are over 40. The probability that one of these 20 subjects will be chosen is 20/255, or .078.

Answer: 4/51

Step-by-step explanation:

20 divided by 255 gives you 0.0784314 which is 4/51 in fraction form.
