How Do You Calculate Conditional Probability?

Alex gets coffee every weekday afternoon. There are three coffee shops near the Expii office: Starbucks, Dunkin' Donuts, and Crazy Mocha. If Alex gets Crazy Mocha on Day 1, it is nine times as likely that he will get Dunkin' Donuts on Day 2 as it is that he will get Starbucks on Day 2. If the probability of getting Crazy Mocha on Day 1 and Starbucks on Day 2 is $0.04,$ find the probability Alex gets Crazy Mocha on Day 1 and Dunkin' Donuts on Day 2.
