Given that the bag contains 16 eggs, with 7 being rotten, the probability of drawing a rotten egg can be calculated as follows:
Probability = Number of favorable outcomes / Total number of possible outcomes.
Number of favorable outcomes: In this case, the number of favorable outcomes is the number of rotten eggs, which is 7.
Total number of possible outcomes: The total number of possible outcomes is the total number of eggs in the bag, which is 16.
Therefore, the probability of drawing a rotten egg can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes = 7 / 16
