Answer: 0.62

Step-by-step explanation:

Total people= 47

Let A be the event of selecting person was interested in trying the new drink.

Person not interested in trying a sample of a new soft drink (nA')=18

Person interested in trying a sample of a new soft drink (nA)=47-18=29

Thus probability that a randomly selected person was interested in trying the new drink

P (A) = 29/41 = 0.6170 (or) 0.62

Thus, probability that a randomly selected person was interested in trying the new drink is 0.62.

47-18=29 people interested in the new drink

29/47=0.617

0.617*100=61.7% chance
