Final answer:
The state lottery's advertising is not deceptive if it clearly states the $500,000 prize is an annuity and the lump sum is $250,000; lack of transparency could otherwise lead to perceptions of deception.
Step-by-step explanation:
Whether the advertising for the state lottery prize is considered deceptive depends on how the information is presented to potential ticket buyers. If the advertisers clearly state that the $500,000 prize refers to an annuity paid out over time, and the lump sum option is $250,000, then it is not deceptive. However, if they only prominently advertise the $500,000 prize without clear indication of the lump sum being half of that, it can be misleading, leading to perceptions of deceptive advertising. The key is transparency in how the prize options are communicated.
