Final answer:
The odds in favor of getting bonus points in John's smartphone game, with a probability of 8/19 for a bonus, are calculated as 8/11.
Step-by-step explanation:
John is playing a game on his smartphone, and the probability of getting bonus points is 8/19.
To find the odds in favor of getting bonus points, we must compare the probability of getting bonus points to the probability of not getting bonus points.
The probability of not getting bonus points is 1 minus the probability of getting bonus points, which is 11/19.
Therefore, the odds in favor of getting bonus points are the ratio of the probability of getting bonus points to the probability of not getting bonus points, which is 8/11.
