a weather girl predicts there is a 50% chance of rain and a 10% chance that the rain will turn into snow. What is the probability that it will snow?
What on earth is a "weather girl?"
To calculate the probability of an event, we multiply the probabilities of each independent event. In this case, the weather girl predicts a 50% chance of rain and a 10% chance that the rain will turn into snow.
To find the probability that it will snow, we multiply these two probabilities.
Probability of rain = 50% = 0.50
Probability of rain turning into snow = 10% = 0.10
Probability of snow = Probability of rain × Probability of rain turning into snow
= 0.50 × 0.10
= 0.05
Therefore, the probability that it will snow is 0.05, which is equivalent to 5%.
