Answer
Probability that a randomly chosen person will pefer K-pop = 0.2145
Explanation
The probability of an event is given as
[tex]\text{Probability of an event = }\frac{Number\text{ of elements in the event}}{Total\text{ number of elements in the sample space}}[/tex]So, to find the probability that a randomly chosen person will prefer K-pop.
Number of elements in the K-pop event = Number of people that chose K-pop = 77
Number of elements in the sample space = Total number of people surveyed = 77 + 242 + 40
= 359
Probability that a randomly chosen person will pefer K-pop = (77/359)
= 0.2145
Hope this Helps!!!
