Final answer:
The combined probability of it raining and getting a hole in one in golf is found by multiplying the individual probabilities, resulting in a joint probability of 0.032%.
Step-by-step explanation:
To calculate the combined probability of two independent events both occurring, we multiply their probabilities together. The odds of it raining today are given as 40%, which is a probability of 0.4 when used in calculations. The odds of getting a hole in one in golf are 0.08%, which is a probability of 0.0008. Multiplying these probabilities gives us the joint probability of both events occurring.
Joint probability = Probability of rain × Probability of a hole in one
Joint probability = 0.4 × 0.0008 = 0.00032 or 0.032%
Therefore, the odds of it raining and you getting a hole in one on the same day are 0.032%.
