To determine the probability that Macy will pass her driver's test, we need to use the odds given.
Odds are typically represented as a ratio of the number of favorable outcomes to the number of unfavorable outcomes. In this case, the odds are given as 12:13.
To calculate the probability, we divide the number of favorable outcomes (12) by the sum of the favorable (12) and unfavorable (13) outcomes.
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 12 / (12 + 13)
Probability = 12 / 25
Now we can calculate the probability:
Probability = 0.48
Therefore, the correct answer is c) 0.480.
