Final answer:
Linda, a casino gambler, is the most susceptible to the illusion of control phenomenon.
Step-by-step explanation:
The illusion of control phenomenon refers to the tendency of individuals to believe that they have control over random or uncertain events, even when they do not. Among the options given, the most susceptible to the illusion of control phenomenon would be Linda, a casino gambler.
This is because casino gambling involves a considerable amount of luck and randomness, yet gamblers often believe that they can somehow control the outcome of their bets through strategies or superstitions. Although the other options may require skill and expertise, they do not involve the same level of randomness as casino gambling, making Linda more likely to be susceptible to the illusion of control.
